Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147378002, here are decompositions:
- 41 + 2147377961 = 2147378002
- 59 + 2147377943 = 2147378002
- 131 + 2147377871 = 2147378002
- 311 + 2147377691 = 2147378002
- 401 + 2147377601 = 2147378002
- 461 + 2147377541 = 2147378002
- 479 + 2147377523 = 2147378002
- 521 + 2147377481 = 2147378002
Showing the first eight; more decompositions exist.
