Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517502, here are decompositions:

11 + 31517491 = 31517502
61 + 31517441 = 31517502
89 + 31517413 = 31517502
103 + 31517399 = 31517502
109 + 31517393 = 31517502
113 + 31517389 = 31517502
229 + 31517273 = 31517502
271 + 31517231 = 31517502

Showing the first eight; more decompositions exist.
