Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599556, here are decompositions:

3 + 31599553 = 31599556
5 + 31599551 = 31599556
167 + 31599389 = 31599556
383 + 31599173 = 31599556
617 + 31598939 = 31599556
647 + 31598909 = 31599556
683 + 31598873 = 31599556
773 + 31598783 = 31599556

Showing the first eight; more decompositions exist.
