Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73818, here are decompositions:
- 47 + 73771 = 73818
- 61 + 73757 = 73818
- 67 + 73751 = 73818
- 97 + 73721 = 73818
- 109 + 73709 = 73818
- 137 + 73681 = 73818
- 139 + 73679 = 73818
- 167 + 73651 = 73818
Showing the first eight; more decompositions exist.
