Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 174990, here are decompositions:
- 31 + 174959 = 174990
- 47 + 174943 = 174990
- 59 + 174931 = 174990
- 61 + 174929 = 174990
- 73 + 174917 = 174990
- 83 + 174907 = 174990
- 89 + 174901 = 174990
- 97 + 174893 = 174990
Showing the first eight; more decompositions exist.
