Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690648, here are decompositions:

37 + 8690611 = 8690648
97 + 8690551 = 8690648
271 + 8690377 = 8690648
277 + 8690371 = 8690648
331 + 8690317 = 8690648
457 + 8690191 = 8690648
607 + 8690041 = 8690648
661 + 8689987 = 8690648

Showing the first eight; more decompositions exist.
