Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491956, here are decompositions:

5 + 491951 = 491956
83 + 491873 = 491956
89 + 491867 = 491956
137 + 491819 = 491956
167 + 491789 = 491956
173 + 491783 = 491956
317 + 491639 = 491956
419 + 491537 = 491956

Showing the first eight; more decompositions exist.
