Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526862, here are decompositions:
- 43 + 31526819 = 31526862
- 53 + 31526809 = 31526862
- 71 + 31526791 = 31526862
- 89 + 31526773 = 31526862
- 109 + 31526753 = 31526862
- 113 + 31526749 = 31526862
- 131 + 31526731 = 31526862
- 139 + 31526723 = 31526862
Showing the first eight; more decompositions exist.
