Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31946, here are decompositions:
- 73 + 31873 = 31946
- 97 + 31849 = 31946
- 223 + 31723 = 31946
- 283 + 31663 = 31946
- 373 + 31573 = 31946
- 379 + 31567 = 31946
- 433 + 31513 = 31946
- 457 + 31489 = 31946
Showing the first eight; more decompositions exist.
