Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723974, here are decompositions:

23 + 8723951 = 8723974
41 + 8723933 = 8723974
53 + 8723921 = 8723974
71 + 8723903 = 8723974
167 + 8723807 = 8723974
443 + 8723531 = 8723974
491 + 8723483 = 8723974
587 + 8723387 = 8723974

Showing the first eight; more decompositions exist.
