Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637142, here are decompositions:

11 + 8637131 = 8637142
23 + 8637119 = 8637142
83 + 8637059 = 8637142
89 + 8637053 = 8637142
233 + 8636909 = 8637142
383 + 8636759 = 8637142
401 + 8636741 = 8637142
509 + 8636633 = 8637142

Showing the first eight; more decompositions exist.
