Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503956, here are decompositions:

73 + 31503883 = 31503956
103 + 31503853 = 31503956
109 + 31503847 = 31503956
157 + 31503799 = 31503956
223 + 31503733 = 31503956
229 + 31503727 = 31503956
283 + 31503673 = 31503956
313 + 31503643 = 31503956

Showing the first eight; more decompositions exist.
