Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574662, here are decompositions:

5 + 31574657 = 31574662
23 + 31574639 = 31574662
131 + 31574531 = 31574662
173 + 31574489 = 31574662
233 + 31574429 = 31574662
293 + 31574369 = 31574662
359 + 31574303 = 31574662
401 + 31574261 = 31574662

Showing the first eight; more decompositions exist.
