Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724748, here are decompositions:

29 + 8724719 = 8724748
107 + 8724641 = 8724748
251 + 8724497 = 8724748
269 + 8724479 = 8724748
281 + 8724467 = 8724748
311 + 8724437 = 8724748
401 + 8724347 = 8724748
419 + 8724329 = 8724748

Showing the first eight; more decompositions exist.
