Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462844, here are decompositions:

13 + 31462831 = 31462844
37 + 31462807 = 31462844
73 + 31462771 = 31462844
97 + 31462747 = 31462844
241 + 31462603 = 31462844
271 + 31462573 = 31462844
313 + 31462531 = 31462844
337 + 31462507 = 31462844

Showing the first eight; more decompositions exist.
