Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574046, here are decompositions:

5 + 31574041 = 31574046
47 + 31573999 = 31574046
79 + 31573967 = 31574046
89 + 31573957 = 31574046
193 + 31573853 = 31574046
199 + 31573847 = 31574046
223 + 31573823 = 31574046
227 + 31573819 = 31574046

Showing the first eight; more decompositions exist.
