Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603070, here are decompositions:

43 + 31603027 = 31603070
61 + 31603009 = 31603070
97 + 31602973 = 31603070
139 + 31602931 = 31603070
193 + 31602877 = 31603070
211 + 31602859 = 31603070
277 + 31602793 = 31603070
307 + 31602763 = 31603070

Showing the first eight; more decompositions exist.
