Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8610988, here are decompositions:

107 + 8610881 = 8610988
137 + 8610851 = 8610988
251 + 8610737 = 8610988
257 + 8610731 = 8610988
389 + 8610599 = 8610988
431 + 8610557 = 8610988
467 + 8610521 = 8610988
479 + 8610509 = 8610988

Showing the first eight; more decompositions exist.
