Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72930, here are decompositions:
- 7 + 72923 = 72930
- 19 + 72911 = 72930
- 23 + 72907 = 72930
- 29 + 72901 = 72930
- 37 + 72893 = 72930
- 41 + 72889 = 72930
- 47 + 72883 = 72930
- 59 + 72871 = 72930
Showing the first eight; more decompositions exist.
