Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476560, here are decompositions:

13 + 31476547 = 31476560
43 + 31476517 = 31476560
61 + 31476499 = 31476560
103 + 31476457 = 31476560
109 + 31476451 = 31476560
127 + 31476433 = 31476560
211 + 31476349 = 31476560
277 + 31476283 = 31476560

Showing the first eight; more decompositions exist.
