Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534944, here are decompositions:

31 + 31534913 = 31534944
71 + 31534873 = 31534944
73 + 31534871 = 31534944
113 + 31534831 = 31534944
157 + 31534787 = 31534944
191 + 31534753 = 31534944
193 + 31534751 = 31534944
293 + 31534651 = 31534944

Showing the first eight; more decompositions exist.
