Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598588, here are decompositions:

67 + 31598521 = 31598588
139 + 31598449 = 31598588
211 + 31598377 = 31598588
349 + 31598239 = 31598588
397 + 31598191 = 31598588
409 + 31598179 = 31598588
487 + 31598101 = 31598588
577 + 31598011 = 31598588

Showing the first eight; more decompositions exist.
