Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147587442, here are decompositions:
- 3 + 2147587439 = 2147587442
- 73 + 2147587369 = 2147587442
- 79 + 2147587363 = 2147587442
- 199 + 2147587243 = 2147587442
- 283 + 2147587159 = 2147587442
- 331 + 2147587111 = 2147587442
- 433 + 2147587009 = 2147587442
- 439 + 2147587003 = 2147587442
Showing the first eight; more decompositions exist.
