Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517482, here are decompositions:

41 + 31517441 = 31517482
71 + 31517411 = 31517482
83 + 31517399 = 31517482
89 + 31517393 = 31517482
239 + 31517243 = 31517482
251 + 31517231 = 31517482
419 + 31517063 = 31517482
443 + 31517039 = 31517482

Showing the first eight; more decompositions exist.
