Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598802, here are decompositions:

13 + 31598789 = 31598802
19 + 31598783 = 31598802
23 + 31598779 = 31598802
31 + 31598771 = 31598802
101 + 31598701 = 31598802
211 + 31598591 = 31598802
281 + 31598521 = 31598802
283 + 31598519 = 31598802

Showing the first eight; more decompositions exist.
