Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584942, here are decompositions:

41 + 31584901 = 31584942
61 + 31584881 = 31584942
73 + 31584869 = 31584942
89 + 31584853 = 31584942
113 + 31584829 = 31584942
173 + 31584769 = 31584942
229 + 31584713 = 31584942
239 + 31584703 = 31584942

Showing the first eight; more decompositions exist.
