Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524902, here are decompositions:

109 + 31524793 = 31524902
139 + 31524763 = 31524902
181 + 31524721 = 31524902
229 + 31524673 = 31524902
379 + 31524523 = 31524902
433 + 31524469 = 31524902
499 + 31524403 = 31524902
571 + 31524331 = 31524902

Showing the first eight; more decompositions exist.
