Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540964, here are decompositions:
- 3 + 31540961 = 31540964
- 43 + 31540921 = 31540964
- 97 + 31540867 = 31540964
- 127 + 31540837 = 31540964
- 151 + 31540813 = 31540964
- 181 + 31540783 = 31540964
- 241 + 31540723 = 31540964
- 271 + 31540693 = 31540964
Showing the first eight; more decompositions exist.
