Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492504, here are decompositions:

11 + 31492493 = 31492504
83 + 31492421 = 31492504
101 + 31492403 = 31492504
167 + 31492337 = 31492504
227 + 31492277 = 31492504
347 + 31492157 = 31492504
431 + 31492073 = 31492504
443 + 31492061 = 31492504

Showing the first eight; more decompositions exist.
