Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524798, here are decompositions:

5 + 31524793 = 31524798
7 + 31524791 = 31524798
31 + 31524767 = 31524798
157 + 31524641 = 31524798
191 + 31524607 = 31524798
211 + 31524587 = 31524798
229 + 31524569 = 31524798
257 + 31524541 = 31524798

Showing the first eight; more decompositions exist.
