Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527146, here are decompositions:
- 3 + 31527143 = 31527146
- 37 + 31527109 = 31527146
- 193 + 31526953 = 31527146
- 283 + 31526863 = 31527146
- 337 + 31526809 = 31527146
- 373 + 31526773 = 31527146
- 397 + 31526749 = 31527146
- 433 + 31526713 = 31527146
Showing the first eight; more decompositions exist.
