Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612540, here are decompositions:

37 + 8612503 = 8612540
43 + 8612497 = 8612540
61 + 8612479 = 8612540
67 + 8612473 = 8612540
103 + 8612437 = 8612540
127 + 8612413 = 8612540
193 + 8612347 = 8612540
229 + 8612311 = 8612540

Showing the first eight; more decompositions exist.
