Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460718, here are decompositions:

17 + 31460701 = 31460718
41 + 31460677 = 31460718
61 + 31460657 = 31460718
71 + 31460647 = 31460718
109 + 31460609 = 31460718
137 + 31460581 = 31460718
167 + 31460551 = 31460718
181 + 31460537 = 31460718

Showing the first eight; more decompositions exist.
