Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615462, here are decompositions:

23 + 31615439 = 31615462
59 + 31615403 = 31615462
71 + 31615391 = 31615462
149 + 31615313 = 31615462
233 + 31615229 = 31615462
251 + 31615211 = 31615462
269 + 31615193 = 31615462
293 + 31615169 = 31615462

Showing the first eight; more decompositions exist.
