Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574190, here are decompositions:

17 + 31574173 = 31574190
59 + 31574131 = 31574190
83 + 31574107 = 31574190
97 + 31574093 = 31574190
149 + 31574041 = 31574190
191 + 31573999 = 31574190
223 + 31573967 = 31574190
229 + 31573961 = 31574190

Showing the first eight; more decompositions exist.
