Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503048, here are decompositions:

89 + 31502959 = 31503048
107 + 31502941 = 31503048
151 + 31502897 = 31503048
167 + 31502881 = 31503048
191 + 31502857 = 31503048
271 + 31502777 = 31503048
347 + 31502701 = 31503048
349 + 31502699 = 31503048

Showing the first eight; more decompositions exist.
