Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503716, here are decompositions:

3 + 31503713 = 31503716
43 + 31503673 = 31503716
73 + 31503643 = 31503716
157 + 31503559 = 31503716
163 + 31503553 = 31503716
337 + 31503379 = 31503716
373 + 31503343 = 31503716
379 + 31503337 = 31503716

Showing the first eight; more decompositions exist.
