Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504764, here are decompositions:

17 + 31504747 = 31504764
61 + 31504703 = 31504764
73 + 31504691 = 31504764
97 + 31504667 = 31504764
103 + 31504661 = 31504764
113 + 31504651 = 31504764
157 + 31504607 = 31504764
173 + 31504591 = 31504764

Showing the first eight; more decompositions exist.
