Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87938, here are decompositions:
- 7 + 87931 = 87938
- 61 + 87877 = 87938
- 127 + 87811 = 87938
- 199 + 87739 = 87938
- 241 + 87697 = 87938
- 307 + 87631 = 87938
- 349 + 87589 = 87938
- 379 + 87559 = 87938
Showing the first eight; more decompositions exist.
