Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553004, here are decompositions:

5 + 31552999 = 31553004
61 + 31552943 = 31553004
97 + 31552907 = 31553004
113 + 31552891 = 31553004
151 + 31552853 = 31553004
157 + 31552847 = 31553004
173 + 31552831 = 31553004
257 + 31552747 = 31553004

Showing the first eight; more decompositions exist.
