Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503102, here are decompositions:

41 + 31503061 = 31503102
109 + 31502993 = 31503102
139 + 31502963 = 31503102
149 + 31502953 = 31503102
179 + 31502923 = 31503102
359 + 31502743 = 31503102
401 + 31502701 = 31503102
443 + 31502659 = 31503102

Showing the first eight; more decompositions exist.
