Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574308, here are decompositions:

5 + 31574303 = 31574308
11 + 31574297 = 31574308
47 + 31574261 = 31574308
107 + 31574201 = 31574308
347 + 31573961 = 31574308
449 + 31573859 = 31574308
461 + 31573847 = 31574308
809 + 31573499 = 31574308

Showing the first eight; more decompositions exist.
