Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476468, here are decompositions:

7 + 31476461 = 31476468
11 + 31476457 = 31476468
17 + 31476451 = 31476468
19 + 31476449 = 31476468
31 + 31476437 = 31476468
97 + 31476371 = 31476468
151 + 31476317 = 31476468
229 + 31476239 = 31476468

Showing the first eight; more decompositions exist.
