Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589084, here are decompositions:

67 + 31589017 = 31589084
73 + 31589011 = 31589084
127 + 31588957 = 31589084
151 + 31588933 = 31589084
157 + 31588927 = 31589084
271 + 31588813 = 31589084
277 + 31588807 = 31589084
523 + 31588561 = 31589084

Showing the first eight; more decompositions exist.
