Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574364, here are decompositions:

37 + 31574327 = 31574364
61 + 31574303 = 31574364
67 + 31574297 = 31574364
103 + 31574261 = 31574364
131 + 31574233 = 31574364
163 + 31574201 = 31574364
191 + 31574173 = 31574364
233 + 31574131 = 31574364

Showing the first eight; more decompositions exist.
