Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588374, here are decompositions:

5 + 31588369 = 31588374
7 + 31588367 = 31588374
17 + 31588357 = 31588374
23 + 31588351 = 31588374
43 + 31588331 = 31588374
53 + 31588321 = 31588374
61 + 31588313 = 31588374
67 + 31588307 = 31588374

Showing the first eight; more decompositions exist.
