Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527240, here are decompositions:
- 7 + 31527233 = 31527240
- 29 + 31527211 = 31527240
- 47 + 31527193 = 31527240
- 67 + 31527173 = 31527240
- 83 + 31527157 = 31527240
- 89 + 31527151 = 31527240
- 97 + 31527143 = 31527240
- 109 + 31527131 = 31527240
Showing the first eight; more decompositions exist.
