Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507228, here are decompositions:
- 17 + 31507211 = 31507228
- 29 + 31507199 = 31507228
- 47 + 31507181 = 31507228
- 89 + 31507139 = 31507228
- 191 + 31507037 = 31507228
- 251 + 31506977 = 31507228
- 317 + 31506911 = 31507228
- 419 + 31506809 = 31507228
Showing the first eight; more decompositions exist.
