Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503046, here are decompositions:

53 + 31502993 = 31503046
83 + 31502963 = 31503046
149 + 31502897 = 31503046
269 + 31502777 = 31503046
347 + 31502699 = 31503046
359 + 31502687 = 31503046
557 + 31502489 = 31503046
563 + 31502483 = 31503046

Showing the first eight; more decompositions exist.
