Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540300, here are decompositions:
- 3 + 31540297 = 31540300
- 59 + 31540241 = 31540300
- 83 + 31540217 = 31540300
- 89 + 31540211 = 31540300
- 137 + 31540163 = 31540300
- 191 + 31540109 = 31540300
- 269 + 31540031 = 31540300
- 293 + 31540007 = 31540300
Showing the first eight; more decompositions exist.
