Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576844, here are decompositions:

67 + 31576777 = 31576844
163 + 31576681 = 31576844
367 + 31576477 = 31576844
433 + 31576411 = 31576844
577 + 31576267 = 31576844
613 + 31576231 = 31576844
643 + 31576201 = 31576844
727 + 31576117 = 31576844

Showing the first eight; more decompositions exist.
