Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724836, here are decompositions:

37 + 8724799 = 8724836
97 + 8724739 = 8724836
139 + 8724697 = 8724836
193 + 8724643 = 8724836
277 + 8724559 = 8724836
349 + 8724487 = 8724836
577 + 8724259 = 8724836
613 + 8724223 = 8724836

Showing the first eight; more decompositions exist.
