Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535400, here are decompositions:
- 19 + 31535381 = 31535400
- 23 + 31535377 = 31535400
- 59 + 31535341 = 31535400
- 73 + 31535327 = 31535400
- 79 + 31535321 = 31535400
- 89 + 31535311 = 31535400
- 137 + 31535263 = 31535400
- 167 + 31535233 = 31535400
Showing the first eight; more decompositions exist.
