Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476478, here are decompositions:

17 + 31476461 = 31476478
29 + 31476449 = 31476478
41 + 31476437 = 31476478
107 + 31476371 = 31476478
227 + 31476251 = 31476478
239 + 31476239 = 31476478
359 + 31476119 = 31476478
419 + 31476059 = 31476478

Showing the first eight; more decompositions exist.
