Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583202, here are decompositions:

31 + 31583171 = 31583202
43 + 31583159 = 31583202
71 + 31583131 = 31583202
151 + 31583051 = 31583202
179 + 31583023 = 31583202
241 + 31582961 = 31583202
251 + 31582951 = 31583202
271 + 31582931 = 31583202

Showing the first eight; more decompositions exist.
