Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61902, here are decompositions:
- 23 + 61879 = 61902
- 31 + 61871 = 61902
- 41 + 61861 = 61902
- 59 + 61843 = 61902
- 83 + 61819 = 61902
- 89 + 61813 = 61902
- 151 + 61751 = 61902
- 173 + 61729 = 61902
Showing the first eight; more decompositions exist.
