Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131924, here are decompositions:
- 31 + 131893 = 131924
- 127 + 131797 = 131924
- 181 + 131743 = 131924
- 193 + 131731 = 131924
- 211 + 131713 = 131924
- 223 + 131701 = 131924
- 283 + 131641 = 131924
- 307 + 131617 = 131924
Showing the first eight; more decompositions exist.
