Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583226, here are decompositions:

67 + 31583159 = 31583226
79 + 31583147 = 31583226
89 + 31583137 = 31583226
139 + 31583087 = 31583226
179 + 31583047 = 31583226
193 + 31583033 = 31583226
277 + 31582949 = 31583226
313 + 31582913 = 31583226

Showing the first eight; more decompositions exist.
