Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147457848, here are decompositions:
- 7 + 2147457841 = 2147457848
- 31 + 2147457817 = 2147457848
- 37 + 2147457811 = 2147457848
- 79 + 2147457769 = 2147457848
- 139 + 2147457709 = 2147457848
- 331 + 2147457517 = 2147457848
- 379 + 2147457469 = 2147457848
- 409 + 2147457439 = 2147457848
Showing the first eight; more decompositions exist.
