Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72110, here are decompositions:
- 7 + 72103 = 72110
- 19 + 72091 = 72110
- 37 + 72073 = 72110
- 67 + 72043 = 72110
- 79 + 72031 = 72110
- 127 + 71983 = 72110
- 139 + 71971 = 72110
- 163 + 71947 = 72110
Showing the first eight; more decompositions exist.
