Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493598, here are decompositions:

5 + 31493593 = 31493598
29 + 31493569 = 31493598
41 + 31493557 = 31493598
79 + 31493519 = 31493598
131 + 31493467 = 31493598
151 + 31493447 = 31493598
179 + 31493419 = 31493598
251 + 31493347 = 31493598

Showing the first eight; more decompositions exist.
