Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724772, here are decompositions:

53 + 8724719 = 8724772
59 + 8724713 = 8724772
131 + 8724641 = 8724772
293 + 8724479 = 8724772
311 + 8724461 = 8724772
401 + 8724371 = 8724772
443 + 8724329 = 8724772
449 + 8724323 = 8724772

Showing the first eight; more decompositions exist.
