Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156784, here are decompositions:
- 3 + 156781 = 156784
- 101 + 156683 = 156784
- 107 + 156677 = 156784
- 113 + 156671 = 156784
- 191 + 156593 = 156784
- 263 + 156521 = 156784
- 293 + 156491 = 156784
- 317 + 156467 = 156784
Showing the first eight; more decompositions exist.
