Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481192, here are decompositions:

3 + 31481189 = 31481192
13 + 31481179 = 31481192
79 + 31481113 = 31481192
181 + 31481011 = 31481192
229 + 31480963 = 31481192
313 + 31480879 = 31481192
331 + 31480861 = 31481192
499 + 31480693 = 31481192

Showing the first eight; more decompositions exist.
