Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61272, here are decompositions:
- 11 + 61261 = 61272
- 19 + 61253 = 61272
- 41 + 61231 = 61272
- 61 + 61211 = 61272
- 103 + 61169 = 61272
- 131 + 61141 = 61272
- 151 + 61121 = 61272
- 173 + 61099 = 61272
Showing the first eight; more decompositions exist.
