Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598434, here are decompositions:

11 + 31598423 = 31598434
17 + 31598417 = 31598434
53 + 31598381 = 31598434
71 + 31598363 = 31598434
107 + 31598327 = 31598434
113 + 31598321 = 31598434
167 + 31598267 = 31598434
173 + 31598261 = 31598434

Showing the first eight; more decompositions exist.
