Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543030, here are decompositions:

11 + 31543019 = 31543030
59 + 31542971 = 31543030
89 + 31542941 = 31543030
149 + 31542881 = 31543030
173 + 31542857 = 31543030
263 + 31542767 = 31543030
353 + 31542677 = 31543030
443 + 31542587 = 31543030

Showing the first eight; more decompositions exist.
