Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590002, here are decompositions:

19 + 31589983 = 31590002
79 + 31589923 = 31590002
229 + 31589773 = 31590002
271 + 31589731 = 31590002
463 + 31589539 = 31590002
541 + 31589461 = 31590002
601 + 31589401 = 31590002
643 + 31589359 = 31590002

Showing the first eight; more decompositions exist.
