Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598422, here are decompositions:

3 + 31598419 = 31598422
5 + 31598417 = 31598422
41 + 31598381 = 31598422
59 + 31598363 = 31598422
101 + 31598321 = 31598422
281 + 31598141 = 31598422
389 + 31598033 = 31598422
461 + 31597961 = 31598422

Showing the first eight; more decompositions exist.
