Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742698, here are decompositions:

61 + 8742637 = 8742698
127 + 8742571 = 8742698
157 + 8742541 = 8742698
199 + 8742499 = 8742698
229 + 8742469 = 8742698
277 + 8742421 = 8742698
331 + 8742367 = 8742698
439 + 8742259 = 8742698

Showing the first eight; more decompositions exist.
