Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72084, here are decompositions:
- 7 + 72077 = 72084
- 11 + 72073 = 72084
- 31 + 72053 = 72084
- 37 + 72047 = 72084
- 41 + 72043 = 72084
- 53 + 72031 = 72084
- 97 + 71987 = 72084
- 101 + 71983 = 72084
Showing the first eight; more decompositions exist.
