Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629742, here are decompositions:

3 + 8629739 = 8629742
31 + 8629711 = 8629742
61 + 8629681 = 8629742
181 + 8629561 = 8629742
313 + 8629429 = 8629742
409 + 8629333 = 8629742
463 + 8629279 = 8629742
571 + 8629171 = 8629742

Showing the first eight; more decompositions exist.
