Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739648, here are decompositions:

11 + 8739637 = 8739648
31 + 8739617 = 8739648
41 + 8739607 = 8739648
149 + 8739499 = 8739648
157 + 8739491 = 8739648
167 + 8739481 = 8739648
251 + 8739397 = 8739648
257 + 8739391 = 8739648

Showing the first eight; more decompositions exist.
