Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739418, here are decompositions:

29 + 8739389 = 8739418
59 + 8739359 = 8739418
137 + 8739281 = 8739418
251 + 8739167 = 8739418
461 + 8738957 = 8739418
617 + 8738801 = 8739418
659 + 8738759 = 8739418
827 + 8738591 = 8739418

Showing the first eight; more decompositions exist.
