Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490296, here are decompositions:

59 + 31490237 = 31490296
107 + 31490189 = 31490296
197 + 31490099 = 31490296
239 + 31490057 = 31490296
347 + 31489949 = 31490296
353 + 31489943 = 31490296
479 + 31489817 = 31490296
587 + 31489709 = 31490296

Showing the first eight; more decompositions exist.
