Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527350, here are decompositions:
- 7 + 31527343 = 31527350
- 73 + 31527277 = 31527350
- 97 + 31527253 = 31527350
- 103 + 31527247 = 31527350
- 139 + 31527211 = 31527350
- 157 + 31527193 = 31527350
- 193 + 31527157 = 31527350
- 199 + 31527151 = 31527350
Showing the first eight; more decompositions exist.
