Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475192, here are decompositions:

3 + 31475189 = 31475192
61 + 31475131 = 31475192
103 + 31475089 = 31475192
109 + 31475083 = 31475192
139 + 31475053 = 31475192
163 + 31475029 = 31475192
193 + 31474999 = 31475192
211 + 31474981 = 31475192

Showing the first eight; more decompositions exist.
