Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582922, here are decompositions:

31 + 31582891 = 31582922
103 + 31582819 = 31582922
193 + 31582729 = 31582922
313 + 31582609 = 31582922
409 + 31582513 = 31582922
433 + 31582489 = 31582922
523 + 31582399 = 31582922
601 + 31582321 = 31582922

Showing the first eight; more decompositions exist.
