Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472854, here are decompositions:

3 + 31472851 = 31472854
5 + 31472849 = 31472854
41 + 31472813 = 31472854
47 + 31472807 = 31472854
131 + 31472723 = 31472854
191 + 31472663 = 31472854
263 + 31472591 = 31472854
317 + 31472537 = 31472854

Showing the first eight; more decompositions exist.
