Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597432, here are decompositions:

149 + 31597283 = 31597432
179 + 31597253 = 31597432
233 + 31597199 = 31597432
281 + 31597151 = 31597432
311 + 31597121 = 31597432
389 + 31597043 = 31597432
401 + 31597031 = 31597432
509 + 31596923 = 31597432

Showing the first eight; more decompositions exist.
