Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690212, here are decompositions:

149 + 8690063 = 8690212
233 + 8689979 = 8690212
263 + 8689949 = 8690212
269 + 8689943 = 8690212
359 + 8689853 = 8690212
389 + 8689823 = 8690212
563 + 8689649 = 8690212
569 + 8689643 = 8690212

Showing the first eight; more decompositions exist.
