Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540454, here are decompositions:
- 13 + 31540441 = 31540454
- 37 + 31540417 = 31540454
- 157 + 31540297 = 31540454
- 193 + 31540261 = 31540454
- 241 + 31540213 = 31540454
- 307 + 31540147 = 31540454
- 331 + 31540123 = 31540454
- 487 + 31539967 = 31540454
Showing the first eight; more decompositions exist.
