Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599854, here are decompositions:

31 + 31599823 = 31599854
43 + 31599811 = 31599854
73 + 31599781 = 31599854
127 + 31599727 = 31599854
151 + 31599703 = 31599854
367 + 31599487 = 31599854
541 + 31599313 = 31599854
547 + 31599307 = 31599854

Showing the first eight; more decompositions exist.
