Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523350, here are decompositions:

3 + 31523347 = 31523350
41 + 31523309 = 31523350
71 + 31523279 = 31523350
83 + 31523267 = 31523350
107 + 31523243 = 31523350
113 + 31523237 = 31523350
149 + 31523201 = 31523350
239 + 31523111 = 31523350

Showing the first eight; more decompositions exist.
