Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523084, here are decompositions:

3 + 31523081 = 31523084
31 + 31523053 = 31523084
97 + 31522987 = 31523084
211 + 31522873 = 31523084
337 + 31522747 = 31523084
367 + 31522717 = 31523084
421 + 31522663 = 31523084
487 + 31522597 = 31523084

Showing the first eight; more decompositions exist.
