Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690726, here are decompositions:

13 + 8690713 = 8690726
43 + 8690683 = 8690726
67 + 8690659 = 8690726
127 + 8690599 = 8690726
313 + 8690413 = 8690726
349 + 8690377 = 8690726
367 + 8690359 = 8690726
409 + 8690317 = 8690726

Showing the first eight; more decompositions exist.
