Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462072, here are decompositions:

3 + 31462069 = 31462072
149 + 31461923 = 31462072
179 + 31461893 = 31462072
281 + 31461791 = 31462072
293 + 31461779 = 31462072
311 + 31461761 = 31462072
419 + 31461653 = 31462072
431 + 31461641 = 31462072

Showing the first eight; more decompositions exist.
