Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589252, here are decompositions:

241 + 31589011 = 31589252
439 + 31588813 = 31589252
691 + 31588561 = 31589252
769 + 31588483 = 31589252
811 + 31588441 = 31589252
853 + 31588399 = 31589252
883 + 31588369 = 31589252
1051 + 31588201 = 31589252

Showing the first eight; more decompositions exist.
