Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504758, here are decompositions:

11 + 31504747 = 31504758
67 + 31504691 = 31504758
97 + 31504661 = 31504758
107 + 31504651 = 31504758
139 + 31504619 = 31504758
151 + 31504607 = 31504758
167 + 31504591 = 31504758
191 + 31504567 = 31504758

Showing the first eight; more decompositions exist.
