Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583074, here are decompositions:

23 + 31583051 = 31583074
41 + 31583033 = 31583074
113 + 31582961 = 31583074
137 + 31582937 = 31583074
167 + 31582907 = 31583074
227 + 31582847 = 31583074
251 + 31582823 = 31583074
293 + 31582781 = 31583074

Showing the first eight; more decompositions exist.
