Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744978, here are decompositions:

37 + 8744941 = 8744978
61 + 8744917 = 8744978
241 + 8744737 = 8744978
271 + 8744707 = 8744978
367 + 8744611 = 8744978
379 + 8744599 = 8744978
421 + 8744557 = 8744978
661 + 8744317 = 8744978

Showing the first eight; more decompositions exist.
