Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588460, here are decompositions:

19 + 31588441 = 31588460
61 + 31588399 = 31588460
103 + 31588357 = 31588460
109 + 31588351 = 31588460
139 + 31588321 = 31588460
157 + 31588303 = 31588460
193 + 31588267 = 31588460
331 + 31588129 = 31588460

Showing the first eight; more decompositions exist.
