Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738242, here are decompositions:

3 + 8738239 = 8738242
11 + 8738231 = 8738242
41 + 8738201 = 8738242
113 + 8738129 = 8738242
263 + 8737979 = 8738242
479 + 8737763 = 8738242
659 + 8737583 = 8738242
719 + 8737523 = 8738242

Showing the first eight; more decompositions exist.
