Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574270, here are decompositions:

37 + 31574233 = 31574270
67 + 31574203 = 31574270
97 + 31574173 = 31574270
139 + 31574131 = 31574270
163 + 31574107 = 31574270
199 + 31574071 = 31574270
223 + 31574047 = 31574270
229 + 31574041 = 31574270

Showing the first eight; more decompositions exist.
