Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541064, here are decompositions:

13 + 31541051 = 31541064
17 + 31541047 = 31541064
43 + 31541021 = 31541064
47 + 31541017 = 31541064
73 + 31540991 = 31541064
103 + 31540961 = 31541064
193 + 31540871 = 31541064
197 + 31540867 = 31541064

Showing the first eight; more decompositions exist.
