Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450300, here are decompositions:

29 + 31450271 = 31450300
53 + 31450247 = 31450300
83 + 31450217 = 31450300
137 + 31450163 = 31450300
197 + 31450103 = 31450300
239 + 31450061 = 31450300
257 + 31450043 = 31450300
269 + 31450031 = 31450300

Showing the first eight; more decompositions exist.
