Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507634, here are decompositions:

43 + 31507591 = 31507634
61 + 31507573 = 31507634
73 + 31507561 = 31507634
127 + 31507507 = 31507634
271 + 31507363 = 31507634
283 + 31507351 = 31507634
313 + 31507321 = 31507634
337 + 31507297 = 31507634

Showing the first eight; more decompositions exist.
