Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742038, here are decompositions:

61 + 8741977 = 8742038
127 + 8741911 = 8742038
199 + 8741839 = 8742038
241 + 8741797 = 8742038
397 + 8741641 = 8742038
601 + 8741437 = 8742038
607 + 8741431 = 8742038
691 + 8741347 = 8742038

Showing the first eight; more decompositions exist.
