Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543162, here are decompositions:

29 + 31543133 = 31543162
59 + 31543103 = 31543162
83 + 31543079 = 31543162
191 + 31542971 = 31543162
251 + 31542911 = 31543162
281 + 31542881 = 31543162
353 + 31542809 = 31543162
503 + 31542659 = 31543162

Showing the first eight; more decompositions exist.
