Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543132, here are decompositions:

29 + 31543103 = 31543132
53 + 31543079 = 31543132
113 + 31543019 = 31543132
191 + 31542941 = 31543132
251 + 31542881 = 31543132
653 + 31542479 = 31543132
773 + 31542359 = 31543132
809 + 31542323 = 31543132

Showing the first eight; more decompositions exist.
