Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690078, here are decompositions:

37 + 8690041 = 8690078
97 + 8689981 = 8690078
109 + 8689969 = 8690078
349 + 8689729 = 8690078
367 + 8689711 = 8690078
421 + 8689657 = 8690078
487 + 8689591 = 8690078
541 + 8689537 = 8690078

Showing the first eight; more decompositions exist.
