Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589722, here are decompositions:

11 + 31589711 = 31589722
29 + 31589693 = 31589722
89 + 31589633 = 31589722
239 + 31589483 = 31589722
383 + 31589339 = 31589722
389 + 31589333 = 31589722
401 + 31589321 = 31589722
419 + 31589303 = 31589722

Showing the first eight; more decompositions exist.
