Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89990, here are decompositions:
- 7 + 89983 = 89990
- 13 + 89977 = 89990
- 31 + 89959 = 89990
- 67 + 89923 = 89990
- 73 + 89917 = 89990
- 151 + 89839 = 89990
- 157 + 89833 = 89990
- 181 + 89809 = 89990
Showing the first eight; more decompositions exist.
