Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72992, here are decompositions:
- 19 + 72973 = 72992
- 43 + 72949 = 72992
- 61 + 72931 = 72992
- 103 + 72889 = 72992
- 109 + 72883 = 72992
- 229 + 72763 = 72992
- 313 + 72679 = 72992
- 331 + 72661 = 72992
Showing the first eight; more decompositions exist.
