Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468830, here are decompositions:

7 + 31468823 = 31468830
37 + 31468793 = 31468830
53 + 31468777 = 31468830
73 + 31468757 = 31468830
103 + 31468727 = 31468830
131 + 31468699 = 31468830
163 + 31468667 = 31468830
193 + 31468637 = 31468830

Showing the first eight; more decompositions exist.
