Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503038, here are decompositions:

79 + 31502959 = 31503038
97 + 31502941 = 31503038
157 + 31502881 = 31503038
181 + 31502857 = 31503038
277 + 31502761 = 31503038
337 + 31502701 = 31503038
349 + 31502689 = 31503038
379 + 31502659 = 31503038

Showing the first eight; more decompositions exist.
