Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475382, here are decompositions:

11 + 31475371 = 31475382
41 + 31475341 = 31475382
61 + 31475321 = 31475382
131 + 31475251 = 31475382
139 + 31475243 = 31475382
151 + 31475231 = 31475382
173 + 31475209 = 31475382
193 + 31475189 = 31475382

Showing the first eight; more decompositions exist.
