Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524616, here are decompositions:

29 + 31524587 = 31524616
47 + 31524569 = 31524616
83 + 31524533 = 31524616
107 + 31524509 = 31524616
197 + 31524419 = 31524616
359 + 31524257 = 31524616
419 + 31524197 = 31524616
449 + 31524167 = 31524616

Showing the first eight; more decompositions exist.
