Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462564, here are decompositions:

11 + 31462553 = 31462564
17 + 31462547 = 31462564
83 + 31462481 = 31462564
113 + 31462451 = 31462564
131 + 31462433 = 31462564
191 + 31462373 = 31462564
251 + 31462313 = 31462564
347 + 31462217 = 31462564

Showing the first eight; more decompositions exist.
