Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528002, here are decompositions:

5 + 31527997 = 31528002
61 + 31527941 = 31528002
71 + 31527931 = 31528002
89 + 31527913 = 31528002
173 + 31527829 = 31528002
293 + 31527709 = 31528002
313 + 31527689 = 31528002
419 + 31527583 = 31528002

Showing the first eight; more decompositions exist.
