Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507466, here are decompositions:

7 + 31507459 = 31507466
103 + 31507363 = 31507466
223 + 31507243 = 31507466
307 + 31507159 = 31507466
349 + 31507117 = 31507466
379 + 31507087 = 31507466
457 + 31507009 = 31507466
643 + 31506823 = 31507466

Showing the first eight; more decompositions exist.
