Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645762, here are decompositions:

3 + 8645759 = 8645762
43 + 8645719 = 8645762
109 + 8645653 = 8645762
271 + 8645491 = 8645762
313 + 8645449 = 8645762
331 + 8645431 = 8645762
409 + 8645353 = 8645762
421 + 8645341 = 8645762

Showing the first eight; more decompositions exist.
