Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588982, here are decompositions:

3 + 31588979 = 31588982
31 + 31588951 = 31588982
283 + 31588699 = 31588982
379 + 31588603 = 31588982
421 + 31588561 = 31588982
499 + 31588483 = 31588982
541 + 31588441 = 31588982
613 + 31588369 = 31588982

Showing the first eight; more decompositions exist.
