Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492132, here are decompositions:

41 + 31492091 = 31492132
53 + 31492079 = 31492132
59 + 31492073 = 31492132
71 + 31492061 = 31492132
101 + 31492031 = 31492132
149 + 31491983 = 31492132
173 + 31491959 = 31492132
239 + 31491893 = 31492132

Showing the first eight; more decompositions exist.
