Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574292, here are decompositions:

31 + 31574261 = 31574292
59 + 31574233 = 31574292
89 + 31574203 = 31574292
193 + 31574099 = 31574292
199 + 31574093 = 31574292
251 + 31574041 = 31574292
271 + 31574021 = 31574292
293 + 31573999 = 31574292

Showing the first eight; more decompositions exist.
