Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72082, here are decompositions:
- 5 + 72077 = 72082
- 29 + 72053 = 72082
- 83 + 71999 = 72082
- 89 + 71993 = 72082
- 149 + 71933 = 72082
- 173 + 71909 = 72082
- 233 + 71849 = 72082
- 239 + 71843 = 72082
Showing the first eight; more decompositions exist.
