Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561498, here are decompositions:
- 37 + 561461 = 561498
- 59 + 561439 = 561498
- 79 + 561419 = 561498
- 89 + 561409 = 561498
- 109 + 561389 = 561498
- 131 + 561367 = 561498
- 139 + 561359 = 561498
- 151 + 561347 = 561498
Showing the first eight; more decompositions exist.
