Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731306, here are decompositions:

5 + 8731301 = 8731306
29 + 8731277 = 8731306
167 + 8731139 = 8731306
197 + 8731109 = 8731306
359 + 8730947 = 8731306
443 + 8730863 = 8731306
449 + 8730857 = 8731306
503 + 8730803 = 8731306

Showing the first eight; more decompositions exist.
