Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464308, here are decompositions:

37 + 31464271 = 31464308
229 + 31464079 = 31464308
241 + 31464067 = 31464308
277 + 31464031 = 31464308
307 + 31464001 = 31464308
349 + 31463959 = 31464308
367 + 31463941 = 31464308
397 + 31463911 = 31464308

Showing the first eight; more decompositions exist.
