Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8650642, here are decompositions:

59 + 8650583 = 8650642
83 + 8650559 = 8650642
101 + 8650541 = 8650642
131 + 8650511 = 8650642
179 + 8650463 = 8650642
191 + 8650451 = 8650642
233 + 8650409 = 8650642
251 + 8650391 = 8650642

Showing the first eight; more decompositions exist.
