Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74840, here are decompositions:
- 13 + 74827 = 74840
- 19 + 74821 = 74840
- 43 + 74797 = 74840
- 61 + 74779 = 74840
- 79 + 74761 = 74840
- 109 + 74731 = 74840
- 127 + 74713 = 74840
- 229 + 74611 = 74840
Showing the first eight; more decompositions exist.
