Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603876, here are decompositions:

47 + 31603829 = 31603876
137 + 31603739 = 31603876
167 + 31603709 = 31603876
233 + 31603643 = 31603876
263 + 31603613 = 31603876
389 + 31603487 = 31603876
449 + 31603427 = 31603876
509 + 31603367 = 31603876

Showing the first eight; more decompositions exist.
