Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489650, here are decompositions:
- 37 + 31489613 = 31489650
- 79 + 31489571 = 31489650
- 109 + 31489541 = 31489650
- 131 + 31489519 = 31489650
- 223 + 31489427 = 31489650
- 233 + 31489417 = 31489650
- 239 + 31489411 = 31489650
- 251 + 31489399 = 31489650
Showing the first eight; more decompositions exist.
