Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684690, here are decompositions:

61 + 8684629 = 8684690
103 + 8684587 = 8684690
211 + 8684479 = 8684690
229 + 8684461 = 8684690
271 + 8684419 = 8684690
283 + 8684407 = 8684690
331 + 8684359 = 8684690
349 + 8684341 = 8684690

Showing the first eight; more decompositions exist.
