Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589112, here are decompositions:

13 + 31589099 = 31589112
43 + 31589069 = 31589112
101 + 31589011 = 31589112
179 + 31588933 = 31589112
419 + 31588693 = 31589112
433 + 31588679 = 31589112
439 + 31588673 = 31589112
509 + 31588603 = 31589112

Showing the first eight; more decompositions exist.
