Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500044, here are decompositions:

151 + 31499893 = 31500044
181 + 31499863 = 31500044
211 + 31499833 = 31500044
241 + 31499803 = 31500044
283 + 31499761 = 31500044
313 + 31499731 = 31500044
547 + 31499497 = 31500044
577 + 31499467 = 31500044

Showing the first eight; more decompositions exist.
