Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550662, here are decompositions:

89 + 31550573 = 31550662
131 + 31550531 = 31550662
191 + 31550471 = 31550662
449 + 31550213 = 31550662
461 + 31550201 = 31550662
509 + 31550153 = 31550662
569 + 31550093 = 31550662
599 + 31550063 = 31550662

Showing the first eight; more decompositions exist.
