Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744870, here are decompositions:

37 + 8744833 = 8744870
163 + 8744707 = 8744870
271 + 8744599 = 8744870
307 + 8744563 = 8744870
313 + 8744557 = 8744870
373 + 8744497 = 8744870
457 + 8744413 = 8744870
601 + 8744269 = 8744870

Showing the first eight; more decompositions exist.
