Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90872, here are decompositions:

31 + 90841 = 90872
79 + 90793 = 90872
163 + 90709 = 90872
193 + 90679 = 90872
241 + 90631 = 90872
349 + 90523 = 90872
373 + 90499 = 90872
433 + 90439 = 90872

Showing the first eight; more decompositions exist.
