Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598844, here are decompositions:

5 + 31598839 = 31598844
61 + 31598783 = 31598844
73 + 31598771 = 31598844
127 + 31598717 = 31598844
157 + 31598687 = 31598844
197 + 31598647 = 31598844
307 + 31598537 = 31598844
331 + 31598513 = 31598844

Showing the first eight; more decompositions exist.
