Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498344, here are decompositions:

37 + 31498307 = 31498344
67 + 31498277 = 31498344
71 + 31498273 = 31498344
127 + 31498217 = 31498344
131 + 31498213 = 31498344
151 + 31498193 = 31498344
193 + 31498151 = 31498344
233 + 31498111 = 31498344

Showing the first eight; more decompositions exist.
