Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523574, here are decompositions:

37 + 31523537 = 31523574
53 + 31523521 = 31523574
97 + 31523477 = 31523574
101 + 31523473 = 31523574
107 + 31523467 = 31523574
113 + 31523461 = 31523574
163 + 31523411 = 31523574
167 + 31523407 = 31523574

Showing the first eight; more decompositions exist.
