Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603082, here are decompositions:

3 + 31603079 = 31603082
73 + 31603009 = 31603082
109 + 31602973 = 31603082
151 + 31602931 = 31603082
223 + 31602859 = 31603082
229 + 31602853 = 31603082
409 + 31602673 = 31603082
421 + 31602661 = 31603082

Showing the first eight; more decompositions exist.
