Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517526, here are decompositions:

59 + 31517467 = 31517526
109 + 31517417 = 31517526
113 + 31517413 = 31517526
127 + 31517399 = 31517526
137 + 31517389 = 31517526
283 + 31517243 = 31517526
463 + 31517063 = 31517526
487 + 31517039 = 31517526

Showing the first eight; more decompositions exist.
