Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503944, here are decompositions:

13 + 31503931 = 31503944
61 + 31503883 = 31503944
97 + 31503847 = 31503944
103 + 31503841 = 31503944
193 + 31503751 = 31503944
211 + 31503733 = 31503944
271 + 31503673 = 31503944
313 + 31503631 = 31503944

Showing the first eight; more decompositions exist.
