Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31451032, here are decompositions:

3 + 31451029 = 31451032
71 + 31450961 = 31451032
83 + 31450949 = 31451032
191 + 31450841 = 31451032
251 + 31450781 = 31451032
269 + 31450763 = 31451032
293 + 31450739 = 31451032
311 + 31450721 = 31451032

Showing the first eight; more decompositions exist.
