Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541976, here are decompositions:
- 5 + 31541971 = 31541976
- 43 + 31541933 = 31541976
- 73 + 31541903 = 31541976
- 83 + 31541893 = 31541976
- 107 + 31541869 = 31541976
- 149 + 31541827 = 31541976
- 239 + 31541737 = 31541976
- 269 + 31541707 = 31541976
Showing the first eight; more decompositions exist.
