Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724282, here are decompositions:

13 + 8724269 = 8724282
19 + 8724263 = 8724282
23 + 8724259 = 8724282
29 + 8724253 = 8724282
41 + 8724241 = 8724282
59 + 8724223 = 8724282
101 + 8724181 = 8724282
113 + 8724169 = 8724282

Showing the first eight; more decompositions exist.
