Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476402, here are decompositions:
- 11 + 31476391 = 31476402
- 19 + 31476383 = 31476402
- 29 + 31476373 = 31476402
- 31 + 31476371 = 31476402
- 53 + 31476349 = 31476402
- 59 + 31476343 = 31476402
- 151 + 31476251 = 31476402
- 163 + 31476239 = 31476402
Showing the first eight; more decompositions exist.
