Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724394, here are decompositions:

17 + 8724377 = 8724394
23 + 8724371 = 8724394
47 + 8724347 = 8724394
71 + 8724323 = 8724394
83 + 8724311 = 8724394
101 + 8724293 = 8724394
131 + 8724263 = 8724394
233 + 8724161 = 8724394

Showing the first eight; more decompositions exist.
