Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705198, here are decompositions:

31 + 8705167 = 8705198
157 + 8705041 = 8705198
277 + 8704921 = 8705198
421 + 8704777 = 8705198
487 + 8704711 = 8705198
499 + 8704699 = 8705198
547 + 8704651 = 8705198
577 + 8704621 = 8705198

Showing the first eight; more decompositions exist.
