Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598340, here are decompositions:

13 + 31598327 = 31598340
19 + 31598321 = 31598340
41 + 31598299 = 31598340
61 + 31598279 = 31598340
73 + 31598267 = 31598340
79 + 31598261 = 31598340
101 + 31598239 = 31598340
113 + 31598227 = 31598340

Showing the first eight; more decompositions exist.
