Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90188, here are decompositions:
- 61 + 90127 = 90188
- 67 + 90121 = 90188
- 157 + 90031 = 90188
- 181 + 90007 = 90188
- 199 + 89989 = 90188
- 211 + 89977 = 90188
- 229 + 89959 = 90188
- 271 + 89917 = 90188
Showing the first eight; more decompositions exist.
