Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523246, here are decompositions:

3 + 31523243 = 31523246
19 + 31523227 = 31523246
37 + 31523209 = 31523246
103 + 31523143 = 31523246
127 + 31523119 = 31523246
193 + 31523053 = 31523246
373 + 31522873 = 31523246
499 + 31522747 = 31523246

Showing the first eight; more decompositions exist.
