Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599644, here are decompositions:

157 + 31599487 = 31599644
331 + 31599313 = 31599644
337 + 31599307 = 31599644
397 + 31599247 = 31599644
487 + 31599157 = 31599644
541 + 31599103 = 31599644
691 + 31598953 = 31599644
733 + 31598911 = 31599644

Showing the first eight; more decompositions exist.
