Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624346, here are decompositions:

3 + 31624343 = 31624346
7 + 31624339 = 31624346
199 + 31624147 = 31624346
277 + 31624069 = 31624346
367 + 31623979 = 31624346
379 + 31623967 = 31624346
643 + 31623703 = 31624346
739 + 31623607 = 31624346

Showing the first eight; more decompositions exist.
