Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742098, here are decompositions:

31 + 8742067 = 8742098
61 + 8742037 = 8742098
109 + 8741989 = 8742098
151 + 8741947 = 8742098
349 + 8741749 = 8742098
457 + 8741641 = 8742098
577 + 8741521 = 8742098
619 + 8741479 = 8742098

Showing the first eight; more decompositions exist.
