Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462616, here are decompositions:

7 + 31462609 = 31462616
13 + 31462603 = 31462616
37 + 31462579 = 31462616
43 + 31462573 = 31462616
109 + 31462507 = 31462616
277 + 31462339 = 31462616
349 + 31462267 = 31462616
547 + 31462069 = 31462616

Showing the first eight; more decompositions exist.
