Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463862, here are decompositions:

5 + 31463857 = 31463862
13 + 31463849 = 31463862
19 + 31463843 = 31463862
83 + 31463779 = 31463862
103 + 31463759 = 31463862
149 + 31463713 = 31463862
173 + 31463689 = 31463862
181 + 31463681 = 31463862

Showing the first eight; more decompositions exist.
