Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68420, here are decompositions:
- 31 + 68389 = 68420
- 109 + 68311 = 68420
- 139 + 68281 = 68420
- 181 + 68239 = 68420
- 193 + 68227 = 68420
- 211 + 68209 = 68420
- 307 + 68113 = 68420
- 349 + 68071 = 68420
Showing the first eight; more decompositions exist.
