Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61144, here are decompositions:
- 3 + 61141 = 61144
- 23 + 61121 = 61144
- 53 + 61091 = 61144
- 101 + 61043 = 61144
- 113 + 61031 = 61144
- 137 + 61007 = 61144
- 191 + 60953 = 61144
- 227 + 60917 = 61144
Showing the first eight; more decompositions exist.
