Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739442, here are decompositions:

11 + 8739431 = 8739442
53 + 8739389 = 8739442
83 + 8739359 = 8739442
233 + 8739209 = 8739442
389 + 8739053 = 8739442
419 + 8739023 = 8739442
479 + 8738963 = 8739442
599 + 8738843 = 8739442

Showing the first eight; more decompositions exist.
