Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589152, here are decompositions:

53 + 31589099 = 31589152
83 + 31589069 = 31589152
173 + 31588979 = 31589152
443 + 31588709 = 31589152
479 + 31588673 = 31589152
509 + 31588643 = 31589152
521 + 31588631 = 31589152
659 + 31588493 = 31589152

Showing the first eight; more decompositions exist.
