Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90020, here are decompositions:
- 3 + 90017 = 90020
- 13 + 90007 = 90020
- 19 + 90001 = 90020
- 31 + 89989 = 90020
- 37 + 89983 = 90020
- 43 + 89977 = 90020
- 61 + 89959 = 90020
- 97 + 89923 = 90020
Showing the first eight; more decompositions exist.
