Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507484, here are decompositions:

163 + 31507321 = 31507484
241 + 31507243 = 31507484
367 + 31507117 = 31507484
397 + 31507087 = 31507484
577 + 31506907 = 31507484
643 + 31506841 = 31507484
661 + 31506823 = 31507484
691 + 31506793 = 31507484

Showing the first eight; more decompositions exist.
