Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472564, here are decompositions:

127 + 31472437 = 31472564
271 + 31472293 = 31472564
373 + 31472191 = 31472564
397 + 31472167 = 31472564
421 + 31472143 = 31472564
433 + 31472131 = 31472564
457 + 31472107 = 31472564
523 + 31472041 = 31472564

Showing the first eight; more decompositions exist.
