Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450964, here are decompositions:

3 + 31450961 = 31450964
67 + 31450897 = 31450964
73 + 31450891 = 31450964
163 + 31450801 = 31450964
241 + 31450723 = 31450964
421 + 31450543 = 31450964
541 + 31450423 = 31450964
577 + 31450387 = 31450964

Showing the first eight; more decompositions exist.
