Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507334, here are decompositions:

13 + 31507321 = 31507334
37 + 31507297 = 31507334
541 + 31506793 = 31507334
757 + 31506577 = 31507334
811 + 31506523 = 31507334
823 + 31506511 = 31507334
967 + 31506367 = 31507334
1051 + 31506283 = 31507334

Showing the first eight; more decompositions exist.
