Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498232, here are decompositions:

19 + 31498213 = 31498232
43 + 31498189 = 31498232
109 + 31498123 = 31498232
163 + 31498069 = 31498232
193 + 31498039 = 31498232
223 + 31498009 = 31498232
229 + 31498003 = 31498232
349 + 31497883 = 31498232

Showing the first eight; more decompositions exist.
