Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475362, here are decompositions:

41 + 31475321 = 31475362
131 + 31475231 = 31475362
173 + 31475189 = 31475362
251 + 31475111 = 31475362
263 + 31475099 = 31475362
293 + 31475069 = 31475362
353 + 31475009 = 31475362
431 + 31474931 = 31475362

Showing the first eight; more decompositions exist.
