Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713990, here are decompositions:

29 + 8713961 = 8713990
59 + 8713931 = 8713990
71 + 8713919 = 8713990
167 + 8713823 = 8713990
179 + 8713811 = 8713990
227 + 8713763 = 8713990
269 + 8713721 = 8713990
281 + 8713709 = 8713990

Showing the first eight; more decompositions exist.
