Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67490, here are decompositions:
- 13 + 67477 = 67490
- 37 + 67453 = 67490
- 43 + 67447 = 67490
- 61 + 67429 = 67490
- 79 + 67411 = 67490
- 151 + 67339 = 67490
- 229 + 67261 = 67490
- 271 + 67219 = 67490
Showing the first eight; more decompositions exist.
