Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603002, here are decompositions:

29 + 31602973 = 31603002
43 + 31602959 = 31603002
71 + 31602931 = 31603002
103 + 31602899 = 31603002
139 + 31602863 = 31603002
149 + 31602853 = 31603002
199 + 31602803 = 31603002
239 + 31602763 = 31603002

Showing the first eight; more decompositions exist.
