Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25784, here are decompositions:
- 13 + 25771 = 25784
- 37 + 25747 = 25784
- 43 + 25741 = 25784
- 67 + 25717 = 25784
- 127 + 25657 = 25784
- 151 + 25633 = 25784
- 163 + 25621 = 25784
- 181 + 25603 = 25784
Showing the first eight; more decompositions exist.
