Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507348, here are decompositions:

29 + 31507319 = 31507348
137 + 31507211 = 31507348
149 + 31507199 = 31507348
167 + 31507181 = 31507348
239 + 31507109 = 31507348
311 + 31507037 = 31507348
419 + 31506929 = 31507348
461 + 31506887 = 31507348

Showing the first eight; more decompositions exist.
