Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472504, here are decompositions:

3 + 31472501 = 31472504
67 + 31472437 = 31472504
211 + 31472293 = 31472504
313 + 31472191 = 31472504
337 + 31472167 = 31472504
373 + 31472131 = 31472504
397 + 31472107 = 31472504
463 + 31472041 = 31472504

Showing the first eight; more decompositions exist.
