Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726978, here are decompositions:

61 + 8726917 = 8726978
241 + 8726737 = 8726978
307 + 8726671 = 8726978
331 + 8726647 = 8726978
367 + 8726611 = 8726978
409 + 8726569 = 8726978
457 + 8726521 = 8726978
499 + 8726479 = 8726978

Showing the first eight; more decompositions exist.
