Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499044, here are decompositions:

11 + 31499033 = 31499044
23 + 31499021 = 31499044
41 + 31499003 = 31499044
53 + 31498991 = 31499044
113 + 31498931 = 31499044
131 + 31498913 = 31499044
191 + 31498853 = 31499044
197 + 31498847 = 31499044

Showing the first eight; more decompositions exist.
