Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598998, here are decompositions:

59 + 31598939 = 31598998
71 + 31598927 = 31598998
89 + 31598909 = 31598998
131 + 31598867 = 31598998
227 + 31598771 = 31598998
281 + 31598717 = 31598998
311 + 31598687 = 31598998
461 + 31598537 = 31598998

Showing the first eight; more decompositions exist.
