Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61040, here are decompositions:
- 13 + 61027 = 61040
- 79 + 60961 = 61040
- 97 + 60943 = 61040
- 103 + 60937 = 61040
- 127 + 60913 = 61040
- 139 + 60901 = 61040
- 151 + 60889 = 61040
- 181 + 60859 = 61040
Showing the first eight; more decompositions exist.
