Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507204, here are decompositions:

5 + 31507199 = 31507204
23 + 31507181 = 31507204
167 + 31507037 = 31507204
227 + 31506977 = 31507204
293 + 31506911 = 31507204
317 + 31506887 = 31507204
383 + 31506821 = 31507204
461 + 31506743 = 31507204

Showing the first eight; more decompositions exist.
