Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589692, here are decompositions:

59 + 31589633 = 31589692
131 + 31589561 = 31589692
179 + 31589513 = 31589692
269 + 31589423 = 31589692
353 + 31589339 = 31589692
359 + 31589333 = 31589692
389 + 31589303 = 31589692
401 + 31589291 = 31589692

Showing the first eight; more decompositions exist.
