Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599452, here are decompositions:

13 + 31599439 = 31599452
103 + 31599349 = 31599452
139 + 31599313 = 31599452
193 + 31599259 = 31599452
349 + 31599103 = 31599452
463 + 31598989 = 31599452
499 + 31598953 = 31599452
541 + 31598911 = 31599452

Showing the first eight; more decompositions exist.
