Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61072, here are decompositions:
- 29 + 61043 = 61072
- 41 + 61031 = 61072
- 71 + 61001 = 61072
- 149 + 60923 = 61072
- 173 + 60899 = 61072
- 251 + 60821 = 61072
- 293 + 60779 = 61072
- 311 + 60761 = 61072
Showing the first eight; more decompositions exist.
