Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475292, here are decompositions:

5 + 31475287 = 31475292
41 + 31475251 = 31475292
61 + 31475231 = 31475292
83 + 31475209 = 31475292
103 + 31475189 = 31475292
151 + 31475141 = 31475292
181 + 31475111 = 31475292
193 + 31475099 = 31475292

Showing the first eight; more decompositions exist.
