Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90740, here are decompositions:

31 + 90709 = 90740
37 + 90703 = 90740
43 + 90697 = 90740
61 + 90679 = 90740
109 + 90631 = 90740
157 + 90583 = 90740
193 + 90547 = 90740
211 + 90529 = 90740

Showing the first eight; more decompositions exist.
