Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503036, here are decompositions:

43 + 31502993 = 31503036
73 + 31502963 = 31503036
83 + 31502953 = 31503036
109 + 31502927 = 31503036
113 + 31502923 = 31503036
139 + 31502897 = 31503036
179 + 31502857 = 31503036
293 + 31502743 = 31503036

Showing the first eight; more decompositions exist.
