Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84072, here are decompositions:
- 5 + 84067 = 84072
- 11 + 84061 = 84072
- 13 + 84059 = 84072
- 19 + 84053 = 84072
- 61 + 84011 = 84072
- 89 + 83983 = 84072
- 103 + 83969 = 84072
- 139 + 83933 = 84072
Showing the first eight; more decompositions exist.
