Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522400, here are decompositions:
- 37 + 31522363 = 31522400
- 43 + 31522357 = 31522400
- 61 + 31522339 = 31522400
- 73 + 31522327 = 31522400
- 103 + 31522297 = 31522400
- 157 + 31522243 = 31522400
- 181 + 31522219 = 31522400
- 193 + 31522207 = 31522400
Showing the first eight; more decompositions exist.
