Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977840, here are decompositions:
- 37 + 977803 = 977840
- 79 + 977761 = 977840
- 211 + 977629 = 977840
- 229 + 977611 = 977840
- 433 + 977407 = 977840
- 541 + 977299 = 977840
- 571 + 977269 = 977840
- 601 + 977239 = 977840
Showing the first eight; more decompositions exist.
