Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589852, here are decompositions:

79 + 31589773 = 31589852
193 + 31589659 = 31589852
241 + 31589611 = 31589852
313 + 31589539 = 31589852
379 + 31589473 = 31589852
499 + 31589353 = 31589852
523 + 31589329 = 31589852
601 + 31589251 = 31589852

Showing the first eight; more decompositions exist.
