Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524764, here are decompositions:

43 + 31524721 = 31524764
157 + 31524607 = 31524764
223 + 31524541 = 31524764
241 + 31524523 = 31524764
421 + 31524343 = 31524764
433 + 31524331 = 31524764
463 + 31524301 = 31524764
487 + 31524277 = 31524764

Showing the first eight; more decompositions exist.
