Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503134, here are decompositions:

31 + 31503103 = 31503134
73 + 31503061 = 31503134
181 + 31502953 = 31503134
193 + 31502941 = 31503134
211 + 31502923 = 31503134
277 + 31502857 = 31503134
373 + 31502761 = 31503134
433 + 31502701 = 31503134

Showing the first eight; more decompositions exist.
