Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577414, here are decompositions:

13 + 31577401 = 31577414
31 + 31577383 = 31577414
61 + 31577353 = 31577414
151 + 31577263 = 31577414
181 + 31577233 = 31577414
241 + 31577173 = 31577414
283 + 31577131 = 31577414
331 + 31577083 = 31577414

Showing the first eight; more decompositions exist.
