Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584998, here are decompositions:

31 + 31584967 = 31584998
37 + 31584961 = 31584998
97 + 31584901 = 31584998
229 + 31584769 = 31584998
241 + 31584757 = 31584998
331 + 31584667 = 31584998
397 + 31584601 = 31584998
421 + 31584577 = 31584998

Showing the first eight; more decompositions exist.
