Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5380, here are decompositions:

29 + 5351 = 5380
47 + 5333 = 5380
71 + 5309 = 5380
83 + 5297 = 5380
101 + 5279 = 5380
107 + 5273 = 5380
149 + 5231 = 5380
191 + 5189 = 5380

Showing the first eight; more decompositions exist.

A staple of calculator humor since pocket calculators put digits in front of bored students.

Position in π

The digit sequence 5380 first appears in π at position 14,079 of the decimal expansion (the 14,079ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
