Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534146, here are decompositions:
- 5 + 31534141 = 31534146
- 29 + 31534117 = 31534146
- 43 + 31534103 = 31534146
- 67 + 31534079 = 31534146
- 73 + 31534073 = 31534146
- 79 + 31534067 = 31534146
- 89 + 31534057 = 31534146
- 113 + 31534033 = 31534146
Showing the first eight; more decompositions exist.
