Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539228, here are decompositions:

37 + 31539191 = 31539228
139 + 31539089 = 31539228
167 + 31539061 = 31539228
181 + 31539047 = 31539228
241 + 31538987 = 31539228
277 + 31538951 = 31539228
401 + 31538827 = 31539228
421 + 31538807 = 31539228

Showing the first eight; more decompositions exist.
