Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506064, here are decompositions:

3 + 31506061 = 31506064
71 + 31505993 = 31506064
137 + 31505927 = 31506064
251 + 31505813 = 31506064
257 + 31505807 = 31506064
263 + 31505801 = 31506064
281 + 31505783 = 31506064
431 + 31505633 = 31506064

Showing the first eight; more decompositions exist.
