Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596542, here are decompositions:

31 + 31596511 = 31596542
139 + 31596403 = 31596542
151 + 31596391 = 31596542
163 + 31596379 = 31596542
349 + 31596193 = 31596542
379 + 31596163 = 31596542
421 + 31596121 = 31596542
613 + 31595929 = 31596542

Showing the first eight; more decompositions exist.
