Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61278, here are decompositions:
- 17 + 61261 = 61278
- 47 + 61231 = 61278
- 67 + 61211 = 61278
- 109 + 61169 = 61278
- 127 + 61151 = 61278
- 137 + 61141 = 61278
- 149 + 61129 = 61278
- 157 + 61121 = 61278
Showing the first eight; more decompositions exist.
