Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472956, here are decompositions:

29 + 31472927 = 31472956
89 + 31472867 = 31472956
107 + 31472849 = 31472956
149 + 31472807 = 31472956
233 + 31472723 = 31472956
257 + 31472699 = 31472956
293 + 31472663 = 31472956
419 + 31472537 = 31472956

Showing the first eight; more decompositions exist.
