Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488366, here are decompositions:

37 + 31488329 = 31488366
43 + 31488323 = 31488366
67 + 31488299 = 31488366
73 + 31488293 = 31488366
109 + 31488257 = 31488366
139 + 31488227 = 31488366
163 + 31488203 = 31488366
229 + 31488137 = 31488366

Showing the first eight; more decompositions exist.
