Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 134442, here are decompositions:
- 5 + 134437 = 134442
- 41 + 134401 = 134442
- 43 + 134399 = 134442
- 71 + 134371 = 134442
- 73 + 134369 = 134442
- 79 + 134363 = 134442
- 83 + 134359 = 134442
- 89 + 134353 = 134442
Showing the first eight; more decompositions exist.
