Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540360, here are decompositions:
- 17 + 31540343 = 31540360
- 149 + 31540211 = 31540360
- 179 + 31540181 = 31540360
- 197 + 31540163 = 31540360
- 251 + 31540109 = 31540360
- 347 + 31540013 = 31540360
- 353 + 31540007 = 31540360
- 389 + 31539971 = 31540360
Showing the first eight; more decompositions exist.
