Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546744, here are decompositions:

3 + 31546741 = 31546744
23 + 31546721 = 31546744
83 + 31546661 = 31546744
107 + 31546637 = 31546744
191 + 31546553 = 31546744
293 + 31546451 = 31546744
443 + 31546301 = 31546744
461 + 31546283 = 31546744

Showing the first eight; more decompositions exist.
