Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540404, here are decompositions:
- 41 + 31540363 = 31540404
- 61 + 31540343 = 31540404
- 107 + 31540297 = 31540404
- 163 + 31540241 = 31540404
- 191 + 31540213 = 31540404
- 193 + 31540211 = 31540404
- 197 + 31540207 = 31540404
- 223 + 31540181 = 31540404
Showing the first eight; more decompositions exist.
