Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539162, here are decompositions:
- 19 + 31539143 = 31539162
- 73 + 31539089 = 31539162
- 79 + 31539083 = 31539162
- 89 + 31539073 = 31539162
- 101 + 31539061 = 31539162
- 211 + 31538951 = 31539162
- 373 + 31538789 = 31539162
- 383 + 31538779 = 31539162
Showing the first eight; more decompositions exist.
