Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586698, here are decompositions:

29 + 31586669 = 31586698
71 + 31586627 = 31586698
107 + 31586591 = 31586698
197 + 31586501 = 31586698
251 + 31586447 = 31586698
347 + 31586351 = 31586698
359 + 31586339 = 31586698
461 + 31586237 = 31586698

Showing the first eight; more decompositions exist.
