Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988402, here are decompositions:
- 59 + 988343 = 988402
- 83 + 988319 = 988402
- 89 + 988313 = 988402
- 131 + 988271 = 988402
- 293 + 988109 = 988402
- 419 + 987983 = 988402
- 431 + 987971 = 988402
- 461 + 987941 = 988402
Showing the first eight; more decompositions exist.
