Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507396, here are decompositions:

29 + 31507367 = 31507396
113 + 31507283 = 31507396
197 + 31507199 = 31507396
257 + 31507139 = 31507396
359 + 31507037 = 31507396
419 + 31506977 = 31507396
467 + 31506929 = 31507396
509 + 31506887 = 31507396

Showing the first eight; more decompositions exist.
