Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159778, here are decompositions:
- 5 + 159773 = 159778
- 41 + 159737 = 159778
- 71 + 159707 = 159778
- 107 + 159671 = 159778
- 149 + 159629 = 159778
- 239 + 159539 = 159778
- 257 + 159521 = 159778
- 347 + 159431 = 159778
Showing the first eight; more decompositions exist.
