Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742068, here are decompositions:

31 + 8742037 = 8742068
79 + 8741989 = 8742068
157 + 8741911 = 8742068
229 + 8741839 = 8742068
271 + 8741797 = 8742068
547 + 8741521 = 8742068
631 + 8741437 = 8742068
739 + 8741329 = 8742068

Showing the first eight; more decompositions exist.
