Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724412, here are decompositions:

41 + 8724371 = 8724412
83 + 8724329 = 8724412
89 + 8724323 = 8724412
101 + 8724311 = 8724412
149 + 8724263 = 8724412
251 + 8724161 = 8724412
269 + 8724143 = 8724412
311 + 8724101 = 8724412

Showing the first eight; more decompositions exist.
