Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10990, here are decompositions:
- 3 + 10987 = 10990
- 11 + 10979 = 10990
- 17 + 10973 = 10990
- 41 + 10949 = 10990
- 53 + 10937 = 10990
- 101 + 10889 = 10990
- 107 + 10883 = 10990
- 131 + 10859 = 10990
Showing the first eight; more decompositions exist.
