Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503846, here are decompositions:

5 + 31503841 = 31503846
37 + 31503809 = 31503846
47 + 31503799 = 31503846
67 + 31503779 = 31503846
97 + 31503749 = 31503846
113 + 31503733 = 31503846
173 + 31503673 = 31503846
277 + 31503569 = 31503846

Showing the first eight; more decompositions exist.
