Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87944, here are decompositions:
- 13 + 87931 = 87944
- 67 + 87877 = 87944
- 151 + 87793 = 87944
- 193 + 87751 = 87944
- 223 + 87721 = 87944
- 313 + 87631 = 87944
- 331 + 87613 = 87944
- 397 + 87547 = 87944
Showing the first eight; more decompositions exist.
