Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523204, here are decompositions:

3 + 31523201 = 31523204
43 + 31523161 = 31523204
61 + 31523143 = 31523204
73 + 31523131 = 31523204
151 + 31523053 = 31523204
331 + 31522873 = 31523204
457 + 31522747 = 31523204
487 + 31522717 = 31523204

Showing the first eight; more decompositions exist.
