Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590396, here are decompositions:

43 + 31590353 = 31590396
53 + 31590343 = 31590396
83 + 31590313 = 31590396
127 + 31590269 = 31590396
263 + 31590133 = 31590396
307 + 31590089 = 31590396
359 + 31590037 = 31590396
389 + 31590007 = 31590396

Showing the first eight; more decompositions exist.
