Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574236, here are decompositions:

3 + 31574233 = 31574236
137 + 31574099 = 31574236
269 + 31573967 = 31574236
383 + 31573853 = 31574236
389 + 31573847 = 31574236
443 + 31573793 = 31574236
479 + 31573757 = 31574236
557 + 31573679 = 31574236

Showing the first eight; more decompositions exist.
