Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488796, here are decompositions:

29 + 31488767 = 31488796
149 + 31488647 = 31488796
233 + 31488563 = 31488796
239 + 31488557 = 31488796
389 + 31488407 = 31488796
467 + 31488329 = 31488796
503 + 31488293 = 31488796
569 + 31488227 = 31488796

Showing the first eight; more decompositions exist.
