Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503710, here are decompositions:

37 + 31503673 = 31503710
67 + 31503643 = 31503710
79 + 31503631 = 31503710
151 + 31503559 = 31503710
157 + 31503553 = 31503710
181 + 31503529 = 31503710
241 + 31503469 = 31503710
331 + 31503379 = 31503710

Showing the first eight; more decompositions exist.
