Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627464, here are decompositions:

53 + 31627411 = 31627464
73 + 31627391 = 31627464
107 + 31627357 = 31627464
131 + 31627333 = 31627464
227 + 31627237 = 31627464
263 + 31627201 = 31627464
313 + 31627151 = 31627464
331 + 31627133 = 31627464

Showing the first eight; more decompositions exist.
