Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524854, here are decompositions:

61 + 31524793 = 31524854
181 + 31524673 = 31524854
211 + 31524643 = 31524854
313 + 31524541 = 31524854
331 + 31524523 = 31524854
337 + 31524517 = 31524854
523 + 31524331 = 31524854
577 + 31524277 = 31524854

Showing the first eight; more decompositions exist.
