Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540134, here are decompositions:
- 11 + 31540123 = 31540134
- 71 + 31540063 = 31540134
- 103 + 31540031 = 31540134
- 127 + 31540007 = 31540134
- 163 + 31539971 = 31540134
- 167 + 31539967 = 31540134
- 233 + 31539901 = 31540134
- 271 + 31539863 = 31540134
Showing the first eight; more decompositions exist.
