Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574052, here are decompositions:

5 + 31574047 = 31574052
11 + 31574041 = 31574052
31 + 31574021 = 31574052
53 + 31573999 = 31574052
193 + 31573859 = 31574052
199 + 31573853 = 31574052
229 + 31573823 = 31574052
233 + 31573819 = 31574052

Showing the first eight; more decompositions exist.
