Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67520, here are decompositions:
- 31 + 67489 = 67520
- 43 + 67477 = 67520
- 67 + 67453 = 67520
- 73 + 67447 = 67520
- 109 + 67411 = 67520
- 151 + 67369 = 67520
- 181 + 67339 = 67520
- 307 + 67213 = 67520
Showing the first eight; more decompositions exist.
