Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470400, here are decompositions:
- 41 + 31470359 = 31470400
- 47 + 31470353 = 31470400
- 107 + 31470293 = 31470400
- 179 + 31470221 = 31470400
- 191 + 31470209 = 31470400
- 233 + 31470167 = 31470400
- 257 + 31470143 = 31470400
- 587 + 31469813 = 31470400
Showing the first eight; more decompositions exist.
