Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507552, here are decompositions:

29 + 31507523 = 31507552
149 + 31507403 = 31507552
191 + 31507361 = 31507552
233 + 31507319 = 31507552
269 + 31507283 = 31507552
281 + 31507271 = 31507552
353 + 31507199 = 31507552
443 + 31507109 = 31507552

Showing the first eight; more decompositions exist.
