Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503034, here are decompositions:

41 + 31502993 = 31503034
71 + 31502963 = 31503034
107 + 31502927 = 31503034
137 + 31502897 = 31503034
257 + 31502777 = 31503034
347 + 31502687 = 31503034
593 + 31502441 = 31503034
701 + 31502333 = 31503034

Showing the first eight; more decompositions exist.
