Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7738, here are decompositions:
- 11 + 7727 = 7738
- 47 + 7691 = 7738
- 89 + 7649 = 7738
- 131 + 7607 = 7738
- 149 + 7589 = 7738
- 179 + 7559 = 7738
- 191 + 7547 = 7738
- 197 + 7541 = 7738
Showing the first eight; more decompositions exist.

A staple of calculator humor since pocket calculators put digits in front of bored students.
The digit sequence 7738 first appears in π at position 12,238 of the decimal expansion (the 12,238ordinal-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.
