Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61140, here are decompositions:
- 11 + 61129 = 61140
- 19 + 61121 = 61140
- 41 + 61099 = 61140
- 83 + 61057 = 61140
- 89 + 61051 = 61140
- 97 + 61043 = 61140
- 109 + 61031 = 61140
- 113 + 61027 = 61140
Showing the first eight; more decompositions exist.
