Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624262, here are decompositions:

193 + 31624069 = 31624262
283 + 31623979 = 31624262
331 + 31623931 = 31624262
541 + 31623721 = 31624262
673 + 31623589 = 31624262
739 + 31623523 = 31624262
751 + 31623511 = 31624262
823 + 31623439 = 31624262

Showing the first eight; more decompositions exist.
