Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 97972, here are decompositions:
- 5 + 97967 = 97972
- 11 + 97961 = 97972
- 29 + 97943 = 97972
- 41 + 97931 = 97972
- 53 + 97919 = 97972
- 89 + 97883 = 97972
- 101 + 97871 = 97972
- 113 + 97859 = 97972
Showing the first eight; more decompositions exist.
