Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506326, here are decompositions:

43 + 31506283 = 31506326
79 + 31506247 = 31506326
223 + 31506103 = 31506326
337 + 31505989 = 31506326
367 + 31505959 = 31506326
727 + 31505599 = 31506326
757 + 31505569 = 31506326
853 + 31505473 = 31506326

Showing the first eight; more decompositions exist.
