Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481066, here are decompositions:

103 + 31480963 = 31481066
193 + 31480873 = 31481066
373 + 31480693 = 31481066
937 + 31480129 = 31481066
1117 + 31479949 = 31481066
1237 + 31479829 = 31481066
1249 + 31479817 = 31481066
1297 + 31479769 = 31481066

Showing the first eight; more decompositions exist.
