Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731090, here are decompositions:

59 + 8731031 = 8731090
107 + 8730983 = 8731090
113 + 8730977 = 8731090
197 + 8730893 = 8731090
227 + 8730863 = 8731090
233 + 8730857 = 8731090
239 + 8730851 = 8731090
293 + 8730797 = 8731090

Showing the first eight; more decompositions exist.
