Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589542, here are decompositions:

3 + 31589539 = 31589542
29 + 31589513 = 31589542
59 + 31589483 = 31589542
239 + 31589303 = 31589542
251 + 31589291 = 31589542
359 + 31589183 = 31589542
443 + 31589099 = 31589542
563 + 31588979 = 31589542

Showing the first eight; more decompositions exist.
