Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598698, here are decompositions:

11 + 31598687 = 31598698
29 + 31598669 = 31598698
107 + 31598591 = 31598698
179 + 31598519 = 31598698
239 + 31598459 = 31598698
281 + 31598417 = 31598698
317 + 31598381 = 31598698
419 + 31598279 = 31598698

Showing the first eight; more decompositions exist.
