Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618774, here are decompositions:

37 + 8618737 = 8618774
181 + 8618593 = 8618774
193 + 8618581 = 8618774
331 + 8618443 = 8618774
397 + 8618377 = 8618774
457 + 8618317 = 8618774
487 + 8618287 = 8618774
523 + 8618251 = 8618774

Showing the first eight; more decompositions exist.
