Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72980, here are decompositions:
- 3 + 72977 = 72980
- 7 + 72973 = 72980
- 31 + 72949 = 72980
- 43 + 72937 = 72980
- 73 + 72907 = 72980
- 79 + 72901 = 72980
- 97 + 72883 = 72980
- 109 + 72871 = 72980
Showing the first eight; more decompositions exist.
