Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539096, here are decompositions:
- 7 + 31539089 = 31539096
- 13 + 31539083 = 31539096
- 23 + 31539073 = 31539096
- 53 + 31539043 = 31539096
- 89 + 31539007 = 31539096
- 109 + 31538987 = 31539096
- 269 + 31538827 = 31539096
- 307 + 31538789 = 31539096
Showing the first eight; more decompositions exist.
