Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31487038, here are decompositions:
- 5 + 31487033 = 31487038
- 17 + 31487021 = 31487038
- 71 + 31486967 = 31487038
- 179 + 31486859 = 31487038
- 269 + 31486769 = 31487038
- 311 + 31486727 = 31487038
- 467 + 31486571 = 31487038
- 509 + 31486529 = 31487038
Showing the first eight; more decompositions exist.
