Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588784, here are decompositions:

127 + 31588657 = 31588784
181 + 31588603 = 31588784
223 + 31588561 = 31588784
313 + 31588471 = 31588784
433 + 31588351 = 31588784
463 + 31588321 = 31588784
613 + 31588171 = 31588784
823 + 31587961 = 31588784

Showing the first eight; more decompositions exist.
