Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502994, here are decompositions:

31 + 31502963 = 31502994
41 + 31502953 = 31502994
53 + 31502941 = 31502994
67 + 31502927 = 31502994
71 + 31502923 = 31502994
97 + 31502897 = 31502994
113 + 31502881 = 31502994
137 + 31502857 = 31502994

Showing the first eight; more decompositions exist.
