Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492844, here are decompositions:

3 + 31492841 = 31492844
7 + 31492837 = 31492844
43 + 31492801 = 31492844
67 + 31492777 = 31492844
73 + 31492771 = 31492844
181 + 31492663 = 31492844
193 + 31492651 = 31492844
241 + 31492603 = 31492844

Showing the first eight; more decompositions exist.
