Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606598, here are decompositions:

19 + 31606579 = 31606598
61 + 31606537 = 31606598
211 + 31606387 = 31606598
229 + 31606369 = 31606598
337 + 31606261 = 31606598
547 + 31606051 = 31606598
787 + 31605811 = 31606598
1021 + 31605577 = 31606598

Showing the first eight; more decompositions exist.
