Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88890, here are decompositions:

7 + 88883 = 88890
17 + 88873 = 88890
23 + 88867 = 88890
29 + 88861 = 88890
37 + 88853 = 88890
47 + 88843 = 88890
71 + 88819 = 88890
73 + 88817 = 88890

Showing the first eight; more decompositions exist.
