Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66422, here are decompositions:
- 19 + 66403 = 66422
- 61 + 66361 = 66422
- 79 + 66343 = 66422
- 151 + 66271 = 66422
- 313 + 66109 = 66422
- 439 + 65983 = 66422
- 523 + 65899 = 66422
- 541 + 65881 = 66422
Showing the first eight; more decompositions exist.
