Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167810, here are decompositions:

31 + 167779 = 167810
127 + 167683 = 167810
199 + 167611 = 167810
367 + 167443 = 167810
373 + 167437 = 167810
397 + 167413 = 167810
499 + 167311 = 167810
541 + 167269 = 167810

Showing the first eight; more decompositions exist.
