Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583166, here are decompositions:

7 + 31583159 = 31583166
19 + 31583147 = 31583166
29 + 31583137 = 31583166
79 + 31583087 = 31583166
229 + 31582937 = 31583166
269 + 31582897 = 31583166
347 + 31582819 = 31583166
389 + 31582777 = 31583166

Showing the first eight; more decompositions exist.
