Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61090, here are decompositions:
- 47 + 61043 = 61090
- 59 + 61031 = 61090
- 83 + 61007 = 61090
- 89 + 61001 = 61090
- 137 + 60953 = 61090
- 167 + 60923 = 61090
- 173 + 60917 = 61090
- 191 + 60899 = 61090
Showing the first eight; more decompositions exist.
