Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599844, here are decompositions:

71 + 31599773 = 31599844
83 + 31599761 = 31599844
137 + 31599707 = 31599844
173 + 31599671 = 31599844
191 + 31599653 = 31599844
233 + 31599611 = 31599844
281 + 31599563 = 31599844
293 + 31599551 = 31599844

Showing the first eight; more decompositions exist.
