Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85784, here are decompositions:
- 3 + 85781 = 85784
- 67 + 85717 = 85784
- 73 + 85711 = 85784
- 157 + 85627 = 85784
- 163 + 85621 = 85784
- 271 + 85513 = 85784
- 331 + 85453 = 85784
- 337 + 85447 = 85784
Showing the first eight; more decompositions exist.
