Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464782, here are decompositions:

73 + 31464709 = 31464782
163 + 31464619 = 31464782
211 + 31464571 = 31464782
331 + 31464451 = 31464782
373 + 31464409 = 31464782
751 + 31464031 = 31464782
823 + 31463959 = 31464782
1039 + 31463743 = 31464782

Showing the first eight; more decompositions exist.
