Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613472, here are decompositions:
- 31 + 31613441 = 31613472
- 61 + 31613411 = 31613472
- 71 + 31613401 = 31613472
- 73 + 31613399 = 31613472
- 89 + 31613383 = 31613472
- 131 + 31613341 = 31613472
- 139 + 31613333 = 31613472
- 181 + 31613291 = 31613472
Showing the first eight; more decompositions exist.
