Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524266, here are decompositions:

43 + 31524223 = 31524266
73 + 31524193 = 31524266
223 + 31524043 = 31524266
313 + 31523953 = 31524266
349 + 31523917 = 31524266
463 + 31523803 = 31524266
607 + 31523659 = 31524266
619 + 31523647 = 31524266

Showing the first eight; more decompositions exist.
