Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524010, here are decompositions:

71 + 31523939 = 31524010
257 + 31523753 = 31524010
359 + 31523651 = 31524010
431 + 31523579 = 31524010
569 + 31523441 = 31524010
599 + 31523411 = 31524010
701 + 31523309 = 31524010
743 + 31523267 = 31524010

Showing the first eight; more decompositions exist.
