Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507434, here are decompositions:

31 + 31507403 = 31507434
67 + 31507367 = 31507434
71 + 31507363 = 31507434
73 + 31507361 = 31507434
83 + 31507351 = 31507434
113 + 31507321 = 31507434
137 + 31507297 = 31507434
151 + 31507283 = 31507434

Showing the first eight; more decompositions exist.
