Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503024, here are decompositions:

31 + 31502993 = 31503024
61 + 31502963 = 31503024
71 + 31502953 = 31503024
83 + 31502941 = 31503024
97 + 31502927 = 31503024
101 + 31502923 = 31503024
127 + 31502897 = 31503024
167 + 31502857 = 31503024

Showing the first eight; more decompositions exist.
