Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 600, here are decompositions:
- 7 + 593 = 600
- 13 + 587 = 600
- 23 + 577 = 600
- 29 + 571 = 600
- 31 + 569 = 600
- 37 + 563 = 600
- 43 + 557 = 600
- 53 + 547 = 600
Showing the first eight; more decompositions exist.
