Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524570, here are decompositions:

29 + 31524541 = 31524570
37 + 31524533 = 31524570
47 + 31524523 = 31524570
53 + 31524517 = 31524570
61 + 31524509 = 31524570
71 + 31524499 = 31524570
101 + 31524469 = 31524570
151 + 31524419 = 31524570

Showing the first eight; more decompositions exist.
