Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588952, here are decompositions:

19 + 31588933 = 31588952
139 + 31588813 = 31588952
349 + 31588603 = 31588952
601 + 31588351 = 31588952
631 + 31588321 = 31588952
751 + 31588201 = 31588952
823 + 31588129 = 31588952
991 + 31587961 = 31588952

Showing the first eight; more decompositions exist.
