Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712390, here are decompositions:

17 + 8712373 = 8712390
19 + 8712371 = 8712390
23 + 8712367 = 8712390
41 + 8712349 = 8712390
53 + 8712337 = 8712390
67 + 8712323 = 8712390
79 + 8712311 = 8712390
83 + 8712307 = 8712390

Showing the first eight; more decompositions exist.
