Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152490, here are decompositions:
- 29 + 152461 = 152490
- 31 + 152459 = 152490
- 47 + 152443 = 152490
- 61 + 152429 = 152490
- 67 + 152423 = 152490
- 71 + 152419 = 152490
- 73 + 152417 = 152490
- 83 + 152407 = 152490
Showing the first eight; more decompositions exist.
