Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4972, here are decompositions:
- 3 + 4969 = 4972
- 5 + 4967 = 4972
- 29 + 4943 = 4972
- 41 + 4931 = 4972
- 53 + 4919 = 4972
- 83 + 4889 = 4972
- 101 + 4871 = 4972
- 173 + 4799 = 4972
Showing the first eight; more decompositions exist.
