Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497434, here are decompositions:

43 + 31497391 = 31497434
97 + 31497337 = 31497434
151 + 31497283 = 31497434
211 + 31497223 = 31497434
277 + 31497157 = 31497434
307 + 31497127 = 31497434
433 + 31497001 = 31497434
457 + 31496977 = 31497434

Showing the first eight; more decompositions exist.
