Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540360, here are decompositions:

17 + 31540343 = 31540360
149 + 31540211 = 31540360
179 + 31540181 = 31540360
197 + 31540163 = 31540360
251 + 31540109 = 31540360
347 + 31540013 = 31540360
353 + 31540007 = 31540360
389 + 31539971 = 31540360

Showing the first eight; more decompositions exist.
