Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504824, here are decompositions:

5 + 31504819 = 31504824
23 + 31504801 = 31504824
41 + 31504783 = 31504824
157 + 31504667 = 31504824
163 + 31504661 = 31504824
173 + 31504651 = 31504824
233 + 31504591 = 31504824
251 + 31504573 = 31504824

Showing the first eight; more decompositions exist.
