Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589126, here are decompositions:

7 + 31589119 = 31589126
109 + 31589017 = 31589126
193 + 31588933 = 31589126
199 + 31588927 = 31589126
229 + 31588897 = 31589126
313 + 31588813 = 31589126
433 + 31588693 = 31589126
523 + 31588603 = 31589126

Showing the first eight; more decompositions exist.
