Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582998, here are decompositions:

17 + 31582981 = 31582998
37 + 31582961 = 31582998
47 + 31582951 = 31582998
61 + 31582937 = 31582998
67 + 31582931 = 31582998
101 + 31582897 = 31582998
107 + 31582891 = 31582998
151 + 31582847 = 31582998

Showing the first eight; more decompositions exist.
