Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524068, here are decompositions:

19 + 31524049 = 31524068
127 + 31523941 = 31524068
151 + 31523917 = 31524068
229 + 31523839 = 31524068
307 + 31523761 = 31524068
409 + 31523659 = 31524068
421 + 31523647 = 31524068
547 + 31523521 = 31524068

Showing the first eight; more decompositions exist.
