Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582634, here are decompositions:

3 + 31582631 = 31582634
7 + 31582627 = 31582634
103 + 31582531 = 31582634
163 + 31582471 = 31582634
313 + 31582321 = 31582634
367 + 31582267 = 31582634
463 + 31582171 = 31582634
541 + 31582093 = 31582634

Showing the first eight; more decompositions exist.
