Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514624, here are decompositions:

73 + 31514551 = 31514624
151 + 31514473 = 31514624
223 + 31514401 = 31514624
433 + 31514191 = 31514624
523 + 31514101 = 31514624
601 + 31514023 = 31514624
733 + 31513891 = 31514624
751 + 31513873 = 31514624

Showing the first eight; more decompositions exist.
