Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624334, here are decompositions:

3 + 31624331 = 31624334
13 + 31624321 = 31624334
193 + 31624141 = 31624334
331 + 31624003 = 31624334
367 + 31623967 = 31624334
433 + 31623901 = 31624334
613 + 31623721 = 31624334
631 + 31623703 = 31624334

Showing the first eight; more decompositions exist.
