Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507464, here are decompositions:

5 + 31507459 = 31507464
61 + 31507403 = 31507464
97 + 31507367 = 31507464
101 + 31507363 = 31507464
103 + 31507361 = 31507464
113 + 31507351 = 31507464
167 + 31507297 = 31507464
181 + 31507283 = 31507464

Showing the first eight; more decompositions exist.
