Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541168, here are decompositions:
- 7 + 31541161 = 31541168
- 67 + 31541101 = 31541168
- 97 + 31541071 = 31541168
- 151 + 31541017 = 31541168
- 229 + 31540939 = 31541168
- 331 + 31540837 = 31541168
- 499 + 31540669 = 31541168
- 727 + 31540441 = 31541168
Showing the first eight; more decompositions exist.
