Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503006, here are decompositions:

13 + 31502993 = 31503006
43 + 31502963 = 31503006
47 + 31502959 = 31503006
53 + 31502953 = 31503006
79 + 31502927 = 31503006
83 + 31502923 = 31503006
109 + 31502897 = 31503006
149 + 31502857 = 31503006

Showing the first eight; more decompositions exist.
