Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468230, here are decompositions:

7 + 31468223 = 31468230
19 + 31468211 = 31468230
29 + 31468201 = 31468230
61 + 31468169 = 31468230
71 + 31468159 = 31468230
83 + 31468147 = 31468230
163 + 31468067 = 31468230
229 + 31468001 = 31468230

Showing the first eight; more decompositions exist.
