Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524630, here are decompositions:

23 + 31524607 = 31524630
43 + 31524587 = 31524630
61 + 31524569 = 31524630
89 + 31524541 = 31524630
97 + 31524533 = 31524630
107 + 31524523 = 31524630
113 + 31524517 = 31524630
131 + 31524499 = 31524630

Showing the first eight; more decompositions exist.
