Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503834, here are decompositions:

23 + 31503811 = 31503834
83 + 31503751 = 31503834
101 + 31503733 = 31503834
107 + 31503727 = 31503834
191 + 31503643 = 31503834
277 + 31503557 = 31503834
281 + 31503553 = 31503834
491 + 31503343 = 31503834

Showing the first eight; more decompositions exist.
