Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135784, here are decompositions:
- 3 + 135781 = 135784
- 41 + 135743 = 135784
- 53 + 135731 = 135784
- 83 + 135701 = 135784
- 113 + 135671 = 135784
- 137 + 135647 = 135784
- 167 + 135617 = 135784
- 191 + 135593 = 135784
Showing the first eight; more decompositions exist.
