Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27490, here are decompositions:
- 3 + 27487 = 27490
- 11 + 27479 = 27490
- 41 + 27449 = 27490
- 53 + 27437 = 27490
- 59 + 27431 = 27490
- 83 + 27407 = 27490
- 191 + 27299 = 27490
- 251 + 27239 = 27490
Showing the first eight; more decompositions exist.
