Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503726, here are decompositions:

13 + 31503713 = 31503726
53 + 31503673 = 31503726
83 + 31503643 = 31503726
157 + 31503569 = 31503726
167 + 31503559 = 31503726
173 + 31503553 = 31503726
197 + 31503529 = 31503726
257 + 31503469 = 31503726

Showing the first eight; more decompositions exist.
