Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582662, here are decompositions:

29 + 31582633 = 31582662
31 + 31582631 = 31582662
53 + 31582609 = 31582662
61 + 31582601 = 31582662
73 + 31582589 = 31582662
103 + 31582559 = 31582662
109 + 31582553 = 31582662
131 + 31582531 = 31582662

Showing the first eight; more decompositions exist.
