Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498422, here are decompositions:

73 + 31498349 = 31498422
79 + 31498343 = 31498422
149 + 31498273 = 31498422
223 + 31498199 = 31498422
229 + 31498193 = 31498422
233 + 31498189 = 31498422
271 + 31498151 = 31498422
311 + 31498111 = 31498422

Showing the first eight; more decompositions exist.
