Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476474, here are decompositions:

13 + 31476461 = 31476474
17 + 31476457 = 31476474
23 + 31476451 = 31476474
37 + 31476437 = 31476474
41 + 31476433 = 31476474
61 + 31476413 = 31476474
83 + 31476391 = 31476474
101 + 31476373 = 31476474

Showing the first eight; more decompositions exist.
