Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523604, here are decompositions:

5 + 31523599 = 31523604
67 + 31523537 = 31523604
83 + 31523521 = 31523604
127 + 31523477 = 31523604
131 + 31523473 = 31523604
137 + 31523467 = 31523604
163 + 31523441 = 31523604
193 + 31523411 = 31523604

Showing the first eight; more decompositions exist.
