Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999524, here are decompositions:
- 3 + 999521 = 999524
- 73 + 999451 = 999524
- 193 + 999331 = 999524
- 307 + 999217 = 999524
- 433 + 999091 = 999524
- 457 + 999067 = 999524
- 541 + 998983 = 999524
- 577 + 998947 = 999524
Showing the first eight; more decompositions exist.
