Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526742, here are decompositions:
- 11 + 31526731 = 31526742
- 19 + 31526723 = 31526742
- 29 + 31526713 = 31526742
- 53 + 31526689 = 31526742
- 73 + 31526669 = 31526742
- 109 + 31526633 = 31526742
- 139 + 31526603 = 31526742
- 179 + 31526563 = 31526742
Showing the first eight; more decompositions exist.
