Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574358, here are decompositions:

29 + 31574329 = 31574358
31 + 31574327 = 31574358
61 + 31574297 = 31574358
97 + 31574261 = 31574358
157 + 31574201 = 31574358
227 + 31574131 = 31574358
251 + 31574107 = 31574358
311 + 31574047 = 31574358

Showing the first eight; more decompositions exist.
