Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577024, here are decompositions:

7 + 31577017 = 31577024
67 + 31576957 = 31577024
181 + 31576843 = 31577024
541 + 31576483 = 31577024
547 + 31576477 = 31577024
571 + 31576453 = 31577024
607 + 31576417 = 31577024
613 + 31576411 = 31577024

Showing the first eight; more decompositions exist.
