Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468630, here are decompositions:

41 + 31468589 = 31468630
59 + 31468571 = 31468630
71 + 31468559 = 31468630
101 + 31468529 = 31468630
107 + 31468523 = 31468630
113 + 31468517 = 31468630
131 + 31468499 = 31468630
227 + 31468403 = 31468630

Showing the first eight; more decompositions exist.
