Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472414, here are decompositions:

223 + 31472191 = 31472414
271 + 31472143 = 31472414
283 + 31472131 = 31472414
307 + 31472107 = 31472414
373 + 31472041 = 31472414
733 + 31471681 = 31472414
751 + 31471663 = 31472414
823 + 31471591 = 31472414

Showing the first eight; more decompositions exist.
