Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552998, here are decompositions:

79 + 31552919 = 31552998
107 + 31552891 = 31552998
151 + 31552847 = 31552998
167 + 31552831 = 31552998
181 + 31552817 = 31552998
251 + 31552747 = 31552998
271 + 31552727 = 31552998
277 + 31552721 = 31552998

Showing the first eight; more decompositions exist.
