Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42230, here are decompositions:
- 3 + 42227 = 42230
- 7 + 42223 = 42230
- 37 + 42193 = 42230
- 43 + 42187 = 42230
- 61 + 42169 = 42230
- 73 + 42157 = 42230
- 157 + 42073 = 42230
- 211 + 42019 = 42230
Showing the first eight; more decompositions exist.
