Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623902, here are decompositions:

5 + 8623897 = 8623902
19 + 8623883 = 8623902
59 + 8623843 = 8623902
71 + 8623831 = 8623902
101 + 8623801 = 8623902
103 + 8623799 = 8623902
109 + 8623793 = 8623902
139 + 8623763 = 8623902

Showing the first eight; more decompositions exist.
