Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690408, here are decompositions:

31 + 8690377 = 8690408
37 + 8690371 = 8690408
367 + 8690041 = 8690408
421 + 8689987 = 8690408
439 + 8689969 = 8690408
631 + 8689777 = 8690408
751 + 8689657 = 8690408
919 + 8689489 = 8690408

Showing the first eight; more decompositions exist.
