Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690438, here are decompositions:

61 + 8690377 = 8690438
67 + 8690371 = 8690438
79 + 8690359 = 8690438
349 + 8690089 = 8690438
397 + 8690041 = 8690438
457 + 8689981 = 8690438
661 + 8689777 = 8690438
709 + 8689729 = 8690438

Showing the first eight; more decompositions exist.
