Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507410, here are decompositions:

7 + 31507403 = 31507410
43 + 31507367 = 31507410
47 + 31507363 = 31507410
59 + 31507351 = 31507410
89 + 31507321 = 31507410
113 + 31507297 = 31507410
127 + 31507283 = 31507410
139 + 31507271 = 31507410

Showing the first eight; more decompositions exist.
