Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72204, here are decompositions:
- 31 + 72173 = 72204
- 37 + 72167 = 72204
- 43 + 72161 = 72204
- 101 + 72103 = 72204
- 103 + 72101 = 72204
- 113 + 72091 = 72204
- 127 + 72077 = 72204
- 131 + 72073 = 72204
Showing the first eight; more decompositions exist.
