Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598830, here are decompositions:

41 + 31598789 = 31598830
47 + 31598783 = 31598830
59 + 31598771 = 31598830
113 + 31598717 = 31598830
239 + 31598591 = 31598830
293 + 31598537 = 31598830
311 + 31598519 = 31598830
317 + 31598513 = 31598830

Showing the first eight; more decompositions exist.
