Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74900, here are decompositions:
- 3 + 74897 = 74900
- 13 + 74887 = 74900
- 31 + 74869 = 74900
- 43 + 74857 = 74900
- 73 + 74827 = 74900
- 79 + 74821 = 74900
- 103 + 74797 = 74900
- 139 + 74761 = 74900
Showing the first eight; more decompositions exist.
