Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524106, here are decompositions:

59 + 31524047 = 31524106
83 + 31524023 = 31524106
167 + 31523939 = 31524106
353 + 31523753 = 31524106
569 + 31523537 = 31524106
797 + 31523309 = 31524106
827 + 31523279 = 31524106
839 + 31523267 = 31524106

Showing the first eight; more decompositions exist.
