Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71844, here are decompositions:
- 7 + 71837 = 71844
- 23 + 71821 = 71844
- 37 + 71807 = 71844
- 67 + 71777 = 71844
- 83 + 71761 = 71844
- 103 + 71741 = 71844
- 131 + 71713 = 71844
- 137 + 71707 = 71844
Showing the first eight; more decompositions exist.
