Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742158, here are decompositions:

37 + 8742121 = 8742158
181 + 8741977 = 8742158
211 + 8741947 = 8742158
379 + 8741779 = 8742158
409 + 8741749 = 8742158
727 + 8741431 = 8742158
757 + 8741401 = 8742158
787 + 8741371 = 8742158

Showing the first eight; more decompositions exist.
