Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72996, here are decompositions:
- 19 + 72977 = 72996
- 23 + 72973 = 72996
- 37 + 72959 = 72996
- 43 + 72953 = 72996
- 47 + 72949 = 72996
- 59 + 72937 = 72996
- 73 + 72923 = 72996
- 89 + 72907 = 72996
Showing the first eight; more decompositions exist.
