Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739402, here are decompositions:
- 5 + 8739397 = 8739402
- 11 + 8739391 = 8739402
- 13 + 8739389 = 8739402
- 43 + 8739359 = 8739402
- 53 + 8739349 = 8739402
- 71 + 8739331 = 8739402
- 103 + 8739299 = 8739402
- 193 + 8739209 = 8739402
Showing the first eight; more decompositions exist.
