Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574214, here are decompositions:

11 + 31574203 = 31574214
13 + 31574201 = 31574214
41 + 31574173 = 31574214
83 + 31574131 = 31574214
107 + 31574107 = 31574214
167 + 31574047 = 31574214
173 + 31574041 = 31574214
193 + 31574021 = 31574214

Showing the first eight; more decompositions exist.
