Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589232, here are decompositions:

113 + 31589119 = 31589232
163 + 31589069 = 31589232
239 + 31588993 = 31589232
281 + 31588951 = 31589232
419 + 31588813 = 31589232
523 + 31588709 = 31589232
601 + 31588631 = 31589232
709 + 31588523 = 31589232

Showing the first eight; more decompositions exist.
