Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73240, here are decompositions:

  • 3 + 73237 = 73240
  • 59 + 73181 = 73240
  • 107 + 73133 = 73240
  • 113 + 73127 = 73240
  • 149 + 73091 = 73240
  • 179 + 73061 = 73240
  • 197 + 73043 = 73240
  • 227 + 73013 = 73240

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 73240 first appears in π at position 259,571 of the decimal expansion (the 259,571ordinal-suffix:st 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.
