Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74870, here are decompositions:
- 13 + 74857 = 74870
- 43 + 74827 = 74870
- 73 + 74797 = 74870
- 109 + 74761 = 74870
- 139 + 74731 = 74870
- 151 + 74719 = 74870
- 157 + 74713 = 74870
- 163 + 74707 = 74870
Showing the first eight; more decompositions exist.
