Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476486, here are decompositions:

29 + 31476457 = 31476486
37 + 31476449 = 31476486
53 + 31476433 = 31476486
73 + 31476413 = 31476486
103 + 31476383 = 31476486
113 + 31476373 = 31476486
137 + 31476349 = 31476486
317 + 31476169 = 31476486

Showing the first eight; more decompositions exist.
