Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739842, here are decompositions:

19 + 8739823 = 8739842
31 + 8739811 = 8739842
73 + 8739769 = 8739842
103 + 8739739 = 8739842
313 + 8739529 = 8739842
379 + 8739463 = 8739842
409 + 8739433 = 8739842
673 + 8739169 = 8739842

Showing the first eight; more decompositions exist.
