Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463260, here are decompositions:

11 + 31463249 = 31463260
47 + 31463213 = 31463260
113 + 31463147 = 31463260
137 + 31463123 = 31463260
173 + 31463087 = 31463260
197 + 31463063 = 31463260
281 + 31462979 = 31463260
359 + 31462901 = 31463260

Showing the first eight; more decompositions exist.
