Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472444, here are decompositions:

7 + 31472437 = 31472444
151 + 31472293 = 31472444
277 + 31472167 = 31472444
313 + 31472131 = 31472444
337 + 31472107 = 31472444
433 + 31472011 = 31472444
613 + 31471831 = 31472444
733 + 31471711 = 31472444

Showing the first eight; more decompositions exist.
