Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497652, here are decompositions:

83 + 31497569 = 31497652
101 + 31497551 = 31497652
191 + 31497461 = 31497652
293 + 31497359 = 31497652
311 + 31497341 = 31497652
353 + 31497299 = 31497652
359 + 31497293 = 31497652
401 + 31497251 = 31497652

Showing the first eight; more decompositions exist.
