Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498300, here are decompositions:

11 + 31498289 = 31498300
23 + 31498277 = 31498300
47 + 31498253 = 31498300
83 + 31498217 = 31498300
101 + 31498199 = 31498300
107 + 31498193 = 31498300
149 + 31498151 = 31498300
257 + 31498043 = 31498300

Showing the first eight; more decompositions exist.
