Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543190, here are decompositions:

181 + 31543009 = 31543190
199 + 31542991 = 31543190
223 + 31542967 = 31543190
241 + 31542949 = 31543190
313 + 31542877 = 31543190
379 + 31542811 = 31543190
463 + 31542727 = 31543190
487 + 31542703 = 31543190

Showing the first eight; more decompositions exist.
