Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524158, here are decompositions:

67 + 31524091 = 31524158
109 + 31524049 = 31524158
241 + 31523917 = 31524158
277 + 31523881 = 31524158
307 + 31523851 = 31524158
397 + 31523761 = 31524158
409 + 31523749 = 31524158
499 + 31523659 = 31524158

Showing the first eight; more decompositions exist.
