Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463090, here are decompositions:

3 + 31463087 = 31463090
7 + 31463083 = 31463090
13 + 31463077 = 31463090
67 + 31463023 = 31463090
157 + 31462933 = 31463090
181 + 31462909 = 31463090
193 + 31462897 = 31463090
283 + 31462807 = 31463090

Showing the first eight; more decompositions exist.
