Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577846, here are decompositions:

67 + 31577779 = 31577846
73 + 31577773 = 31577846
199 + 31577647 = 31577846
337 + 31577509 = 31577846
373 + 31577473 = 31577846
457 + 31577389 = 31577846
463 + 31577383 = 31577846
523 + 31577323 = 31577846

Showing the first eight; more decompositions exist.
