Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461952, here are decompositions:

3 + 31461949 = 31461952
29 + 31461923 = 31461952
59 + 31461893 = 31461952
101 + 31461851 = 31461952
173 + 31461779 = 31461952
191 + 31461761 = 31461952
311 + 31461641 = 31461952
383 + 31461569 = 31461952

Showing the first eight; more decompositions exist.
