Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464142, here are decompositions:

5 + 31464137 = 31464142
179 + 31463963 = 31464142
233 + 31463909 = 31464142
251 + 31463891 = 31464142
263 + 31463879 = 31464142
293 + 31463849 = 31464142
383 + 31463759 = 31464142
461 + 31463681 = 31464142

Showing the first eight; more decompositions exist.
