Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590662, here are decompositions:

3 + 31590659 = 31590662
13 + 31590649 = 31590662
31 + 31590631 = 31590662
73 + 31590589 = 31590662
79 + 31590583 = 31590662
163 + 31590499 = 31590662
193 + 31590469 = 31590662
199 + 31590463 = 31590662

Showing the first eight; more decompositions exist.
