Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476132, here are decompositions:

13 + 31476119 = 31476132
19 + 31476113 = 31476132
59 + 31476073 = 31476132
73 + 31476059 = 31476132
101 + 31476031 = 31476132
179 + 31475953 = 31476132
223 + 31475909 = 31476132
283 + 31475849 = 31476132

Showing the first eight; more decompositions exist.
