Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724944, here are decompositions:

61 + 8724883 = 8724944
73 + 8724871 = 8724944
97 + 8724847 = 8724944
157 + 8724787 = 8724944
223 + 8724721 = 8724944
313 + 8724631 = 8724944
433 + 8724511 = 8724944
457 + 8724487 = 8724944

Showing the first eight; more decompositions exist.
