Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507454, here are decompositions:

103 + 31507351 = 31507454
157 + 31507297 = 31507454
211 + 31507243 = 31507454
337 + 31507117 = 31507454
367 + 31507087 = 31507454
373 + 31507081 = 31507454
523 + 31506931 = 31507454
547 + 31506907 = 31507454

Showing the first eight; more decompositions exist.
