Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558526, here are decompositions:

7 + 31558519 = 31558526
37 + 31558489 = 31558526
73 + 31558453 = 31558526
127 + 31558399 = 31558526
199 + 31558327 = 31558526
379 + 31558147 = 31558526
397 + 31558129 = 31558526
463 + 31558063 = 31558526

Showing the first eight; more decompositions exist.
