Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476480, here are decompositions:

19 + 31476461 = 31476480
23 + 31476457 = 31476480
29 + 31476451 = 31476480
31 + 31476449 = 31476480
43 + 31476437 = 31476480
47 + 31476433 = 31476480
67 + 31476413 = 31476480
89 + 31476391 = 31476480

Showing the first eight; more decompositions exist.
