Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588434, here are decompositions:

67 + 31588367 = 31588434
83 + 31588351 = 31588434
103 + 31588331 = 31588434
113 + 31588321 = 31588434
127 + 31588307 = 31588434
131 + 31588303 = 31588434
167 + 31588267 = 31588434
181 + 31588253 = 31588434

Showing the first eight; more decompositions exist.
