Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739742, here are decompositions:

3 + 8739739 = 8739742
29 + 8739713 = 8739742
71 + 8739671 = 8739742
239 + 8739503 = 8739742
251 + 8739491 = 8739742
311 + 8739431 = 8739742
353 + 8739389 = 8739742
383 + 8739359 = 8739742

Showing the first eight; more decompositions exist.
