Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640118, here are decompositions:

59 + 8640059 = 8640118
101 + 8640017 = 8640118
131 + 8639987 = 8640118
167 + 8639951 = 8640118
197 + 8639921 = 8640118
269 + 8639849 = 8640118
281 + 8639837 = 8640118
479 + 8639639 = 8640118

Showing the first eight; more decompositions exist.
