Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724538, here are decompositions:

41 + 8724497 = 8724538
59 + 8724479 = 8724538
71 + 8724467 = 8724538
101 + 8724437 = 8724538
167 + 8724371 = 8724538
191 + 8724347 = 8724538
227 + 8724311 = 8724538
269 + 8724269 = 8724538

Showing the first eight; more decompositions exist.
