Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708690, here are decompositions:

73 + 8708617 = 8708690
79 + 8708611 = 8708690
163 + 8708527 = 8708690
181 + 8708509 = 8708690
229 + 8708461 = 8708690
241 + 8708449 = 8708690
421 + 8708269 = 8708690
547 + 8708143 = 8708690

Showing the first eight; more decompositions exist.
