Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497604, here are decompositions:

3 + 31497601 = 31497604
53 + 31497551 = 31497604
113 + 31497491 = 31497604
137 + 31497467 = 31497604
251 + 31497353 = 31497604
263 + 31497341 = 31497604
311 + 31497293 = 31497604
317 + 31497287 = 31497604

Showing the first eight; more decompositions exist.
