Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90780, here are decompositions:

31 + 90749 = 90780
71 + 90709 = 90780
83 + 90697 = 90780
101 + 90679 = 90780
103 + 90677 = 90780
139 + 90641 = 90780
149 + 90631 = 90780
163 + 90617 = 90780

Showing the first eight; more decompositions exist.
