Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690140, here are decompositions:

23 + 8690117 = 8690140
47 + 8690093 = 8690140
71 + 8690069 = 8690140
191 + 8689949 = 8690140
197 + 8689943 = 8690140
317 + 8689823 = 8690140
467 + 8689673 = 8690140
479 + 8689661 = 8690140

Showing the first eight; more decompositions exist.
