Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506264, here are decompositions:

17 + 31506247 = 31506264
71 + 31506193 = 31506264
173 + 31506091 = 31506264
193 + 31506071 = 31506264
233 + 31506031 = 31506264
271 + 31505993 = 31506264
281 + 31505983 = 31506264
337 + 31505927 = 31506264

Showing the first eight; more decompositions exist.
