Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583032, here are decompositions:

71 + 31582961 = 31583032
83 + 31582949 = 31583032
101 + 31582931 = 31583032
251 + 31582781 = 31583032
293 + 31582739 = 31583032
353 + 31582679 = 31583032
359 + 31582673 = 31583032
401 + 31582631 = 31583032

Showing the first eight; more decompositions exist.
