Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574294, here are decompositions:

61 + 31574233 = 31574294
163 + 31574131 = 31574294
223 + 31574071 = 31574294
337 + 31573957 = 31574294
463 + 31573831 = 31574294
541 + 31573753 = 31574294
547 + 31573747 = 31574294
673 + 31573621 = 31574294

Showing the first eight; more decompositions exist.
