Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655212, here are decompositions:

109 + 8655103 = 8655212
271 + 8654941 = 8655212
373 + 8654839 = 8655212
409 + 8654803 = 8655212
439 + 8654773 = 8655212
463 + 8654749 = 8655212
499 + 8654713 = 8655212
523 + 8654689 = 8655212

Showing the first eight; more decompositions exist.
