Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494750, here are decompositions:

13 + 31494737 = 31494750
29 + 31494721 = 31494750
37 + 31494713 = 31494750
43 + 31494707 = 31494750
59 + 31494691 = 31494750
61 + 31494689 = 31494750
71 + 31494679 = 31494750
107 + 31494643 = 31494750

Showing the first eight; more decompositions exist.
