Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655260, here are decompositions:

43 + 8655217 = 8655260
157 + 8655103 = 8655260
223 + 8655037 = 8655260
421 + 8654839 = 8655260
457 + 8654803 = 8655260
487 + 8654773 = 8655260
499 + 8654761 = 8655260
547 + 8654713 = 8655260

Showing the first eight; more decompositions exist.
