Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504770, here are decompositions:

23 + 31504747 = 31504770
67 + 31504703 = 31504770
79 + 31504691 = 31504770
103 + 31504667 = 31504770
109 + 31504661 = 31504770
151 + 31504619 = 31504770
163 + 31504607 = 31504770
179 + 31504591 = 31504770

Showing the first eight; more decompositions exist.
