Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498268, here are decompositions:

79 + 31498189 = 31498268
157 + 31498111 = 31498268
181 + 31498087 = 31498268
199 + 31498069 = 31498268
229 + 31498039 = 31498268
271 + 31497997 = 31498268
337 + 31497931 = 31498268
397 + 31497871 = 31498268

Showing the first eight; more decompositions exist.
