Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724974, here are decompositions:

7 + 8724967 = 8724974
31 + 8724943 = 8724974
103 + 8724871 = 8724974
127 + 8724847 = 8724974
277 + 8724697 = 8724974
331 + 8724643 = 8724974
373 + 8724601 = 8724974
463 + 8724511 = 8724974

Showing the first eight; more decompositions exist.
