Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449734, here are decompositions:

37 + 31449697 = 31449734
61 + 31449673 = 31449734
97 + 31449637 = 31449734
157 + 31449577 = 31449734
163 + 31449571 = 31449734
181 + 31449553 = 31449734
241 + 31449493 = 31449734
271 + 31449463 = 31449734

Showing the first eight; more decompositions exist.
