Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31144, here are decompositions:
- 5 + 31139 = 31144
- 23 + 31121 = 31144
- 53 + 31091 = 31144
- 131 + 31013 = 31144
- 167 + 30977 = 31144
- 173 + 30971 = 31144
- 233 + 30911 = 31144
- 251 + 30893 = 31144
Showing the first eight; more decompositions exist.
