Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460766, here are decompositions:

23 + 31460743 = 31460766
37 + 31460729 = 31460766
89 + 31460677 = 31460766
109 + 31460657 = 31460766
157 + 31460609 = 31460766
229 + 31460537 = 31460766
257 + 31460509 = 31460766
269 + 31460497 = 31460766

Showing the first eight; more decompositions exist.
