Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467480, here are decompositions:
- 13 + 31467467 = 31467480
- 43 + 31467437 = 31467480
- 47 + 31467433 = 31467480
- 61 + 31467419 = 31467480
- 113 + 31467367 = 31467480
- 151 + 31467329 = 31467480
- 179 + 31467301 = 31467480
- 229 + 31467251 = 31467480
Showing the first eight; more decompositions exist.
