Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606472, here are decompositions:

3 + 31606469 = 31606472
43 + 31606429 = 31606472
61 + 31606411 = 31606472
103 + 31606369 = 31606472
193 + 31606279 = 31606472
211 + 31606261 = 31606472
421 + 31606051 = 31606472
661 + 31605811 = 31606472

Showing the first eight; more decompositions exist.
