Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561492, here are decompositions:
- 31 + 561461 = 561492
- 53 + 561439 = 561492
- 73 + 561419 = 561492
- 83 + 561409 = 561492
- 103 + 561389 = 561492
- 149 + 561343 = 561492
- 179 + 561313 = 561492
- 241 + 561251 = 561492
Showing the first eight; more decompositions exist.
