Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724342, here are decompositions:

13 + 8724329 = 8724342
19 + 8724323 = 8724342
23 + 8724319 = 8724342
31 + 8724311 = 8724342
41 + 8724301 = 8724342
59 + 8724283 = 8724342
73 + 8724269 = 8724342
79 + 8724263 = 8724342

Showing the first eight; more decompositions exist.
