Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136488, here are decompositions:
- 5 + 136483 = 136488
- 7 + 136481 = 136488
- 17 + 136471 = 136488
- 41 + 136447 = 136488
- 59 + 136429 = 136488
- 67 + 136421 = 136488
- 71 + 136417 = 136488
- 89 + 136399 = 136488
Showing the first eight; more decompositions exist.
