Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486246, here are decompositions:

17 + 31486229 = 31486246
83 + 31486163 = 31486246
137 + 31486109 = 31486246
293 + 31485953 = 31486246
353 + 31485893 = 31486246
443 + 31485803 = 31486246
479 + 31485767 = 31486246
503 + 31485743 = 31486246

Showing the first eight; more decompositions exist.
