Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475260, here are decompositions:

17 + 31475243 = 31475260
29 + 31475231 = 31475260
71 + 31475189 = 31475260
101 + 31475159 = 31475260
149 + 31475111 = 31475260
191 + 31475069 = 31475260
251 + 31475009 = 31475260
263 + 31474997 = 31475260

Showing the first eight; more decompositions exist.
