Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731862, here are decompositions:

3 + 8731859 = 8731862
31 + 8731831 = 8731862
43 + 8731819 = 8731862
79 + 8731783 = 8731862
151 + 8731711 = 8731862
163 + 8731699 = 8731862
283 + 8731579 = 8731862
331 + 8731531 = 8731862

Showing the first eight; more decompositions exist.
