Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507246, here are decompositions:

3 + 31507243 = 31507246
47 + 31507199 = 31507246
107 + 31507139 = 31507246
137 + 31507109 = 31507246
269 + 31506977 = 31507246
317 + 31506929 = 31507246
359 + 31506887 = 31507246
503 + 31506743 = 31507246

Showing the first eight; more decompositions exist.
