Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505326, here are decompositions:

5 + 31505321 = 31505326
23 + 31505303 = 31505326
29 + 31505297 = 31505326
113 + 31505213 = 31505326
137 + 31505189 = 31505326
227 + 31505099 = 31505326
383 + 31504943 = 31505326
443 + 31504883 = 31505326

Showing the first eight; more decompositions exist.
