Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588718, here are decompositions:

19 + 31588699 = 31588718
61 + 31588657 = 31588718
157 + 31588561 = 31588718
277 + 31588441 = 31588718
349 + 31588369 = 31588718
367 + 31588351 = 31588718
397 + 31588321 = 31588718
547 + 31588171 = 31588718

Showing the first eight; more decompositions exist.
