Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88990, here are decompositions:

53 + 88937 = 88990
71 + 88919 = 88990
107 + 88883 = 88990
137 + 88853 = 88990
173 + 88817 = 88990
179 + 88811 = 88990
191 + 88799 = 88990
197 + 88793 = 88990

Showing the first eight; more decompositions exist.
