Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476494, here are decompositions:

37 + 31476457 = 31476494
43 + 31476451 = 31476494
61 + 31476433 = 31476494
103 + 31476391 = 31476494
151 + 31476343 = 31476494
211 + 31476283 = 31476494
307 + 31476187 = 31476494
337 + 31476157 = 31476494

Showing the first eight; more decompositions exist.
