Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506414, here are decompositions:

41 + 31506373 = 31506414
47 + 31506367 = 31506414
61 + 31506353 = 31506414
83 + 31506331 = 31506414
103 + 31506311 = 31506414
131 + 31506283 = 31506414
151 + 31506263 = 31506414
167 + 31506247 = 31506414

Showing the first eight; more decompositions exist.
