Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497184, here are decompositions:

101 + 31497083 = 31497184
113 + 31497071 = 31497184
227 + 31496957 = 31497184
263 + 31496921 = 31497184
311 + 31496873 = 31497184
401 + 31496783 = 31497184
443 + 31496741 = 31497184
491 + 31496693 = 31497184

Showing the first eight; more decompositions exist.
