Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593002, here are decompositions:

19 + 31592983 = 31593002
31 + 31592971 = 31593002
43 + 31592959 = 31593002
79 + 31592923 = 31593002
193 + 31592809 = 31593002
223 + 31592779 = 31593002
229 + 31592773 = 31593002
241 + 31592761 = 31593002

Showing the first eight; more decompositions exist.
