Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540998, here are decompositions:

7 + 31540991 = 31540998
19 + 31540979 = 31540998
37 + 31540961 = 31540998
59 + 31540939 = 31540998
127 + 31540871 = 31540998
131 + 31540867 = 31540998
211 + 31540787 = 31540998
271 + 31540727 = 31540998

Showing the first eight; more decompositions exist.
