Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476630, here are decompositions:

7 + 31476623 = 31476630
19 + 31476611 = 31476630
23 + 31476607 = 31476630
37 + 31476593 = 31476630
43 + 31476587 = 31476630
79 + 31476551 = 31476630
83 + 31476547 = 31476630
113 + 31476517 = 31476630

Showing the first eight; more decompositions exist.
