Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590600, here are decompositions:

7 + 31590593 = 31590600
11 + 31590589 = 31590600
17 + 31590583 = 31590600
29 + 31590571 = 31590600
43 + 31590557 = 31590600
101 + 31590499 = 31590600
113 + 31590487 = 31590600
131 + 31590469 = 31590600

Showing the first eight; more decompositions exist.
