Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546748, here are decompositions:

7 + 31546741 = 31546748
31 + 31546717 = 31546748
127 + 31546621 = 31546748
151 + 31546597 = 31546748
157 + 31546591 = 31546748
379 + 31546369 = 31546748
397 + 31546351 = 31546748
619 + 31546129 = 31546748

Showing the first eight; more decompositions exist.
