Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731426, here are decompositions:

83 + 8731343 = 8731426
113 + 8731313 = 8731426
149 + 8731277 = 8731426
239 + 8731187 = 8731426
317 + 8731109 = 8731426
443 + 8730983 = 8731426
449 + 8730977 = 8731426
479 + 8730947 = 8731426

Showing the first eight; more decompositions exist.
