Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599750, here are decompositions:

23 + 31599727 = 31599750
43 + 31599707 = 31599750
47 + 31599703 = 31599750
67 + 31599683 = 31599750
79 + 31599671 = 31599750
97 + 31599653 = 31599750
101 + 31599649 = 31599750
139 + 31599611 = 31599750

Showing the first eight; more decompositions exist.
