Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589132, here are decompositions:

13 + 31589119 = 31589132
139 + 31588993 = 31589132
181 + 31588951 = 31589132
199 + 31588933 = 31589132
433 + 31588699 = 31589132
439 + 31588693 = 31589132
571 + 31588561 = 31589132
661 + 31588471 = 31589132

Showing the first eight; more decompositions exist.
