Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45972, here are decompositions:
- 13 + 45959 = 45972
- 19 + 45953 = 45972
- 23 + 45949 = 45972
- 29 + 45943 = 45972
- 79 + 45893 = 45972
- 103 + 45869 = 45972
- 109 + 45863 = 45972
- 131 + 45841 = 45972
Showing the first eight; more decompositions exist.
