Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589090, here are decompositions:

3 + 31589087 = 31589090
73 + 31589017 = 31589090
79 + 31589011 = 31589090
97 + 31588993 = 31589090
139 + 31588951 = 31589090
157 + 31588933 = 31589090
163 + 31588927 = 31589090
193 + 31588897 = 31589090

Showing the first eight; more decompositions exist.
