Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78774, here are decompositions:
- 37 + 78737 = 78774
- 53 + 78721 = 78774
- 61 + 78713 = 78774
- 67 + 78707 = 78774
- 83 + 78691 = 78774
- 131 + 78643 = 78774
- 151 + 78623 = 78774
- 167 + 78607 = 78774
Showing the first eight; more decompositions exist.
