Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607526, here are decompositions:

23 + 31607503 = 31607526
37 + 31607489 = 31607526
53 + 31607473 = 31607526
79 + 31607447 = 31607526
103 + 31607423 = 31607526
127 + 31607399 = 31607526
163 + 31607363 = 31607526
199 + 31607327 = 31607526

Showing the first eight; more decompositions exist.
