Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85472, here are decompositions:
- 3 + 85469 = 85472
- 19 + 85453 = 85472
- 43 + 85429 = 85472
- 61 + 85411 = 85472
- 103 + 85369 = 85472
- 109 + 85363 = 85472
- 139 + 85333 = 85472
- 229 + 85243 = 85472
Showing the first eight; more decompositions exist.
