Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73872, here are decompositions:
- 5 + 73867 = 73872
- 13 + 73859 = 73872
- 23 + 73849 = 73872
- 53 + 73819 = 73872
- 89 + 73783 = 73872
- 101 + 73771 = 73872
- 151 + 73721 = 73872
- 163 + 73709 = 73872
Showing the first eight; more decompositions exist.
