Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615742, here are decompositions:

19 + 8615723 = 8615742
89 + 8615653 = 8615742
151 + 8615591 = 8615742
199 + 8615543 = 8615742
229 + 8615513 = 8615742
251 + 8615491 = 8615742
263 + 8615479 = 8615742
269 + 8615473 = 8615742

Showing the first eight; more decompositions exist.
