Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462486, here are decompositions:

5 + 31462481 = 31462486
47 + 31462439 = 31462486
53 + 31462433 = 31462486
113 + 31462373 = 31462486
137 + 31462349 = 31462486
173 + 31462313 = 31462486
197 + 31462289 = 31462486
269 + 31462217 = 31462486

Showing the first eight; more decompositions exist.
