Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71784, here are decompositions:
- 7 + 71777 = 71784
- 23 + 71761 = 71784
- 43 + 71741 = 71784
- 71 + 71713 = 71784
- 73 + 71711 = 71784
- 113 + 71671 = 71784
- 137 + 71647 = 71784
- 151 + 71633 = 71784
Showing the first eight; more decompositions exist.
