Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724382, here are decompositions:

5 + 8724377 = 8724382
11 + 8724371 = 8724382
53 + 8724329 = 8724382
59 + 8724323 = 8724382
71 + 8724311 = 8724382
89 + 8724293 = 8724382
113 + 8724269 = 8724382
239 + 8724143 = 8724382

Showing the first eight; more decompositions exist.
