Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576488, here are decompositions:

5 + 31576483 = 31576488
11 + 31576477 = 31576488
29 + 31576459 = 31576488
61 + 31576427 = 31576488
71 + 31576417 = 31576488
79 + 31576409 = 31576488
137 + 31576351 = 31576488
199 + 31576289 = 31576488

Showing the first eight; more decompositions exist.
