Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607556, here are decompositions:

5 + 31607551 = 31607556
53 + 31607503 = 31607556
67 + 31607489 = 31607556
83 + 31607473 = 31607556
107 + 31607449 = 31607556
109 + 31607447 = 31607556
157 + 31607399 = 31607556
193 + 31607363 = 31607556

Showing the first eight; more decompositions exist.
