Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493132, here are decompositions:

79 + 31493053 = 31493132
103 + 31493029 = 31493132
199 + 31492933 = 31493132
211 + 31492921 = 31493132
283 + 31492849 = 31493132
331 + 31492801 = 31493132
661 + 31492471 = 31493132
709 + 31492423 = 31493132

Showing the first eight; more decompositions exist.
