Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10890, here are decompositions:
- 7 + 10883 = 10890
- 23 + 10867 = 10890
- 29 + 10861 = 10890
- 31 + 10859 = 10890
- 37 + 10853 = 10890
- 43 + 10847 = 10890
- 53 + 10837 = 10890
- 59 + 10831 = 10890
Showing the first eight; more decompositions exist.
