Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504884, here are decompositions:

11 + 31504873 = 31504884
83 + 31504801 = 31504884
101 + 31504783 = 31504884
137 + 31504747 = 31504884
181 + 31504703 = 31504884
193 + 31504691 = 31504884
223 + 31504661 = 31504884
233 + 31504651 = 31504884

Showing the first eight; more decompositions exist.
