Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613742, here are decompositions:

3 + 8613739 = 8613742
41 + 8613701 = 8613742
281 + 8613461 = 8613742
419 + 8613323 = 8613742
443 + 8613299 = 8613742
461 + 8613281 = 8613742
521 + 8613221 = 8613742
593 + 8613149 = 8613742

Showing the first eight; more decompositions exist.
