Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577734, here are decompositions:

5 + 31577729 = 31577734
17 + 31577717 = 31577734
101 + 31577633 = 31577734
263 + 31577471 = 31577734
317 + 31577417 = 31577734
347 + 31577387 = 31577734
443 + 31577291 = 31577734
653 + 31577081 = 31577734

Showing the first eight; more decompositions exist.
