Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530354, here are decompositions:

5 + 31530349 = 31530354
7 + 31530347 = 31530354
13 + 31530341 = 31530354
43 + 31530311 = 31530354
61 + 31530293 = 31530354
151 + 31530203 = 31530354
157 + 31530197 = 31530354
173 + 31530181 = 31530354

Showing the first eight; more decompositions exist.
