Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464040, here are decompositions:

131 + 31463909 = 31464040
149 + 31463891 = 31464040
191 + 31463849 = 31464040
197 + 31463843 = 31464040
233 + 31463807 = 31464040
281 + 31463759 = 31464040
359 + 31463681 = 31464040
449 + 31463591 = 31464040

Showing the first eight; more decompositions exist.
