Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61172, here are decompositions:
- 3 + 61169 = 61172
- 19 + 61153 = 61172
- 31 + 61141 = 61172
- 43 + 61129 = 61172
- 73 + 61099 = 61172
- 211 + 60961 = 61172
- 229 + 60943 = 61172
- 271 + 60901 = 61172
Showing the first eight; more decompositions exist.
