Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654990, here are decompositions:

31 + 8654959 = 8654990
73 + 8654917 = 8654990
151 + 8654839 = 8654990
181 + 8654809 = 8654990
229 + 8654761 = 8654990
241 + 8654749 = 8654990
277 + 8654713 = 8654990
349 + 8654641 = 8654990

Showing the first eight; more decompositions exist.
