Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543124, here are decompositions:
- 157 + 31542967 = 31543124
- 181 + 31542943 = 31543124
- 313 + 31542811 = 31543124
- 337 + 31542787 = 31543124
- 397 + 31542727 = 31543124
- 421 + 31542703 = 31543124
- 577 + 31542547 = 31543124
- 601 + 31542523 = 31543124
Showing the first eight; more decompositions exist.
