Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460986, here are decompositions:

59 + 31460927 = 31460986
107 + 31460879 = 31460986
113 + 31460873 = 31460986
149 + 31460837 = 31460986
257 + 31460729 = 31460986
269 + 31460717 = 31460986
449 + 31460537 = 31460986
503 + 31460483 = 31460986

Showing the first eight; more decompositions exist.
