Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603092, here are decompositions:

13 + 31603079 = 31603092
19 + 31603073 = 31603092
83 + 31603009 = 31603092
193 + 31602899 = 31603092
229 + 31602863 = 31603092
233 + 31602859 = 31603092
239 + 31602853 = 31603092
401 + 31602691 = 31603092

Showing the first eight; more decompositions exist.
