Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991952, here are decompositions:
- 43 + 991909 = 991952
- 79 + 991873 = 991952
- 211 + 991741 = 991952
- 229 + 991723 = 991952
- 331 + 991621 = 991952
- 349 + 991603 = 991952
- 373 + 991579 = 991952
- 421 + 991531 = 991952
Showing the first eight; more decompositions exist.
