Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61930, here are decompositions:
- 3 + 61927 = 61930
- 59 + 61871 = 61930
- 149 + 61781 = 61930
- 173 + 61757 = 61930
- 179 + 61751 = 61930
- 227 + 61703 = 61930
- 257 + 61673 = 61930
- 263 + 61667 = 61930
Showing the first eight; more decompositions exist.
