Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527230, here are decompositions:
- 19 + 31527211 = 31527230
- 37 + 31527193 = 31527230
- 73 + 31527157 = 31527230
- 79 + 31527151 = 31527230
- 277 + 31526953 = 31527230
- 331 + 31526899 = 31527230
- 337 + 31526893 = 31527230
- 349 + 31526881 = 31527230
Showing the first eight; more decompositions exist.
