Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498404, here are decompositions:

37 + 31498367 = 31498404
61 + 31498343 = 31498404
97 + 31498307 = 31498404
127 + 31498277 = 31498404
131 + 31498273 = 31498404
151 + 31498253 = 31498404
191 + 31498213 = 31498404
211 + 31498193 = 31498404

Showing the first eight; more decompositions exist.
