Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494824, here are decompositions:

7 + 31494817 = 31494824
43 + 31494781 = 31494824
61 + 31494763 = 31494824
103 + 31494721 = 31494824
181 + 31494643 = 31494824
241 + 31494583 = 31494824
271 + 31494553 = 31494824
397 + 31494427 = 31494824

Showing the first eight; more decompositions exist.
