Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506336, here are decompositions:

5 + 31506331 = 31506336
53 + 31506283 = 31506336
73 + 31506263 = 31506336
89 + 31506247 = 31506336
163 + 31506173 = 31506336
233 + 31506103 = 31506336
307 + 31506029 = 31506336
347 + 31505989 = 31506336

Showing the first eight; more decompositions exist.
