Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526390, here are decompositions:
- 3 + 31526387 = 31526390
- 19 + 31526371 = 31526390
- 31 + 31526359 = 31526390
- 73 + 31526317 = 31526390
- 109 + 31526281 = 31526390
- 151 + 31526239 = 31526390
- 163 + 31526227 = 31526390
- 193 + 31526197 = 31526390
Showing the first eight; more decompositions exist.
