Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517662, here are decompositions:

23 + 31517639 = 31517662
83 + 31517579 = 31517662
89 + 31517573 = 31517662
251 + 31517411 = 31517662
263 + 31517399 = 31517662
269 + 31517393 = 31517662
389 + 31517273 = 31517662
419 + 31517243 = 31517662

Showing the first eight; more decompositions exist.
