Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615702, here are decompositions:

113 + 31615589 = 31615702
263 + 31615439 = 31615702
311 + 31615391 = 31615702
359 + 31615343 = 31615702
389 + 31615313 = 31615702
491 + 31615211 = 31615702
509 + 31615193 = 31615702
593 + 31615109 = 31615702

Showing the first eight; more decompositions exist.
