Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40284, here are decompositions:
- 7 + 40277 = 40284
- 31 + 40253 = 40284
- 43 + 40241 = 40284
- 47 + 40237 = 40284
- 53 + 40231 = 40284
- 71 + 40213 = 40284
- 107 + 40177 = 40284
- 131 + 40153 = 40284
Showing the first eight; more decompositions exist.
