Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589030, here are decompositions:

3 + 31589027 = 31589030
13 + 31589017 = 31589030
19 + 31589011 = 31589030
37 + 31588993 = 31589030
73 + 31588957 = 31589030
79 + 31588951 = 31589030
97 + 31588933 = 31589030
103 + 31588927 = 31589030

Showing the first eight; more decompositions exist.
