Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739042, here are decompositions:

19 + 8739023 = 8739042
41 + 8739001 = 8739042
79 + 8738963 = 8739042
113 + 8738929 = 8739042
199 + 8738843 = 8739042
229 + 8738813 = 8739042
233 + 8738809 = 8739042
241 + 8738801 = 8739042

Showing the first eight; more decompositions exist.
