Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476664, here are decompositions:

41 + 31476623 = 31476664
53 + 31476611 = 31476664
71 + 31476593 = 31476664
113 + 31476551 = 31476664
227 + 31476437 = 31476664
251 + 31476413 = 31476664
281 + 31476383 = 31476664
293 + 31476371 = 31476664

Showing the first eight; more decompositions exist.
