Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524906, here are decompositions:

13 + 31524893 = 31524906
43 + 31524863 = 31524906
67 + 31524839 = 31524906
97 + 31524809 = 31524906
109 + 31524797 = 31524906
113 + 31524793 = 31524906
139 + 31524767 = 31524906
229 + 31524677 = 31524906

Showing the first eight; more decompositions exist.
