Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713238, here are decompositions:

97 + 8713141 = 8713238
151 + 8713087 = 8713238
229 + 8713009 = 8713238
241 + 8712997 = 8713238
307 + 8712931 = 8713238
379 + 8712859 = 8713238
487 + 8712751 = 8713238
577 + 8712661 = 8713238

Showing the first eight; more decompositions exist.
