Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574274, here are decompositions:

13 + 31574261 = 31574274
41 + 31574233 = 31574274
71 + 31574203 = 31574274
73 + 31574201 = 31574274
101 + 31574173 = 31574274
167 + 31574107 = 31574274
181 + 31574093 = 31574274
227 + 31574047 = 31574274

Showing the first eight; more decompositions exist.
