Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497524, here are decompositions:

61 + 31497463 = 31497524
211 + 31497313 = 31497524
241 + 31497283 = 31497524
337 + 31497187 = 31497524
367 + 31497157 = 31497524
397 + 31497127 = 31497524
523 + 31497001 = 31497524
547 + 31496977 = 31497524

Showing the first eight; more decompositions exist.
