Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608262, here are decompositions:

113 + 31608149 = 31608262
131 + 31608131 = 31608262
233 + 31608029 = 31608262
293 + 31607969 = 31608262
353 + 31607909 = 31608262
359 + 31607903 = 31608262
431 + 31607831 = 31608262
479 + 31607783 = 31608262

Showing the first eight; more decompositions exist.
