Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610484, here are decompositions:

47 + 31610437 = 31610484
71 + 31610413 = 31610484
131 + 31610353 = 31610484
151 + 31610333 = 31610484
167 + 31610317 = 31610484
193 + 31610291 = 31610484
197 + 31610287 = 31610484
271 + 31610213 = 31610484

Showing the first eight; more decompositions exist.
