Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496150, here are decompositions:

31 + 31496119 = 31496150
67 + 31496083 = 31496150
109 + 31496041 = 31496150
139 + 31496011 = 31496150
229 + 31495921 = 31496150
271 + 31495879 = 31496150
331 + 31495819 = 31496150
349 + 31495801 = 31496150

Showing the first eight; more decompositions exist.
