Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67530, here are decompositions:
- 7 + 67523 = 67530
- 19 + 67511 = 67530
- 31 + 67499 = 67530
- 37 + 67493 = 67530
- 41 + 67489 = 67530
- 53 + 67477 = 67530
- 83 + 67447 = 67530
- 97 + 67433 = 67530
Showing the first eight; more decompositions exist.
