Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476666, here are decompositions:

43 + 31476623 = 31476666
59 + 31476607 = 31476666
73 + 31476593 = 31476666
79 + 31476587 = 31476666
149 + 31476517 = 31476666
157 + 31476509 = 31476666
167 + 31476499 = 31476666
229 + 31476437 = 31476666

Showing the first eight; more decompositions exist.
