Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72242, here are decompositions:
- 13 + 72229 = 72242
- 19 + 72223 = 72242
- 31 + 72211 = 72242
- 73 + 72169 = 72242
- 103 + 72139 = 72242
- 139 + 72103 = 72242
- 151 + 72091 = 72242
- 199 + 72043 = 72242
Showing the first eight; more decompositions exist.
