Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517282, here are decompositions:

271 + 31517011 = 31517282
331 + 31516951 = 31517282
463 + 31516819 = 31517282
613 + 31516669 = 31517282
739 + 31516543 = 31517282
859 + 31516423 = 31517282
1093 + 31516189 = 31517282
1123 + 31516159 = 31517282

Showing the first eight; more decompositions exist.
