Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524100, here are decompositions:

53 + 31524047 = 31524100
89 + 31524011 = 31524100
347 + 31523753 = 31524100
431 + 31523669 = 31524100
449 + 31523651 = 31524100
467 + 31523633 = 31524100
521 + 31523579 = 31524100
563 + 31523537 = 31524100

Showing the first eight; more decompositions exist.
