Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598586, here are decompositions:

43 + 31598543 = 31598586
67 + 31598519 = 31598586
73 + 31598513 = 31598586
127 + 31598459 = 31598586
137 + 31598449 = 31598586
163 + 31598423 = 31598586
167 + 31598419 = 31598586
223 + 31598363 = 31598586

Showing the first eight; more decompositions exist.
