Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450994, here are decompositions:

97 + 31450897 = 31450994
103 + 31450891 = 31450994
151 + 31450843 = 31450994
193 + 31450801 = 31450994
271 + 31450723 = 31450994
373 + 31450621 = 31450994
571 + 31450423 = 31450994
607 + 31450387 = 31450994

Showing the first eight; more decompositions exist.
