Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463830, here are decompositions:

3 + 31463827 = 31463830
23 + 31463807 = 31463830
71 + 31463759 = 31463830
113 + 31463717 = 31463830
149 + 31463681 = 31463830
239 + 31463591 = 31463830
311 + 31463519 = 31463830
347 + 31463483 = 31463830

Showing the first eight; more decompositions exist.
