Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576434, here are decompositions:

7 + 31576427 = 31576434
17 + 31576417 = 31576434
23 + 31576411 = 31576434
31 + 31576403 = 31576434
61 + 31576373 = 31576434
67 + 31576367 = 31576434
83 + 31576351 = 31576434
151 + 31576283 = 31576434

Showing the first eight; more decompositions exist.
