Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623084, here are decompositions:

23 + 31623061 = 31623084
37 + 31623047 = 31623084
43 + 31623041 = 31623084
61 + 31623023 = 31623084
137 + 31622947 = 31623084
151 + 31622933 = 31623084
191 + 31622893 = 31623084
281 + 31622803 = 31623084

Showing the first eight; more decompositions exist.
