Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 462990, here are decompositions:
- 7 + 462983 = 462990
- 37 + 462953 = 462990
- 43 + 462947 = 462990
- 53 + 462937 = 462990
- 79 + 462911 = 462990
- 89 + 462901 = 462990
- 103 + 462887 = 462990
- 109 + 462881 = 462990
Showing the first eight; more decompositions exist.
