Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588670, here are decompositions:

13 + 31588657 = 31588670
67 + 31588603 = 31588670
109 + 31588561 = 31588670
199 + 31588471 = 31588670
229 + 31588441 = 31588670
271 + 31588399 = 31588670
313 + 31588357 = 31588670
349 + 31588321 = 31588670

Showing the first eight; more decompositions exist.
