Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618632, here are decompositions:

41 + 8618591 = 8618632
131 + 8618501 = 8618632
149 + 8618483 = 8618632
293 + 8618339 = 8618632
359 + 8618273 = 8618632
389 + 8618243 = 8618632
419 + 8618213 = 8618632
569 + 8618063 = 8618632

Showing the first eight; more decompositions exist.
