Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620108, here are decompositions:

59 + 8620049 = 8620108
239 + 8619869 = 8620108
251 + 8619857 = 8620108
311 + 8619797 = 8620108
317 + 8619791 = 8620108
389 + 8619719 = 8620108
521 + 8619587 = 8620108
557 + 8619551 = 8620108

Showing the first eight; more decompositions exist.
