Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576934, here are decompositions:

3 + 31576931 = 31576934
43 + 31576891 = 31576934
157 + 31576777 = 31576934
457 + 31576477 = 31576934
523 + 31576411 = 31576934
673 + 31576261 = 31576934
733 + 31576201 = 31576934
997 + 31575937 = 31576934

Showing the first eight; more decompositions exist.
