Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618650, here are decompositions:

11 + 8618639 = 8618650
59 + 8618591 = 8618650
83 + 8618567 = 8618650
149 + 8618501 = 8618650
167 + 8618483 = 8618650
263 + 8618387 = 8618650
311 + 8618339 = 8618650
353 + 8618297 = 8618650

Showing the first eight; more decompositions exist.
