Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31621462, here are decompositions:

233 + 31621229 = 31621462
293 + 31621169 = 31621462
311 + 31621151 = 31621462
419 + 31621043 = 31621462
449 + 31621013 = 31621462
461 + 31621001 = 31621462
641 + 31620821 = 31621462
683 + 31620779 = 31621462

Showing the first eight; more decompositions exist.
