Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598902, here are decompositions:

29 + 31598873 = 31598902
113 + 31598789 = 31598902
131 + 31598771 = 31598902
149 + 31598753 = 31598902
233 + 31598669 = 31598902
311 + 31598591 = 31598902
359 + 31598543 = 31598902
383 + 31598519 = 31598902

Showing the first eight; more decompositions exist.
