Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505366, here are decompositions:

7 + 31505359 = 31505366
37 + 31505329 = 31505366
73 + 31505293 = 31505366
223 + 31505143 = 31505366
229 + 31505137 = 31505366
367 + 31504999 = 31505366
379 + 31504987 = 31505366
457 + 31504909 = 31505366

Showing the first eight; more decompositions exist.
