Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539432, here are decompositions:

11 + 31539421 = 31539432
19 + 31539413 = 31539432
31 + 31539401 = 31539432
79 + 31539353 = 31539432
83 + 31539349 = 31539432
101 + 31539331 = 31539432
103 + 31539329 = 31539432
149 + 31539283 = 31539432

Showing the first eight; more decompositions exist.
