Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583404, here are decompositions:

53 + 31583351 = 31583404
233 + 31583171 = 31583404
257 + 31583147 = 31583404
317 + 31583087 = 31583404
353 + 31583051 = 31583404
443 + 31582961 = 31583404
467 + 31582937 = 31583404
491 + 31582913 = 31583404

Showing the first eight; more decompositions exist.
