Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462476, here are decompositions:

5 + 31462471 = 31462476
37 + 31462439 = 31462476
43 + 31462433 = 31462476
103 + 31462373 = 31462476
113 + 31462363 = 31462476
127 + 31462349 = 31462476
137 + 31462339 = 31462476
163 + 31462313 = 31462476

Showing the first eight; more decompositions exist.
