Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595466, here are decompositions:

59 + 31595407 = 31595466
73 + 31595393 = 31595466
79 + 31595387 = 31595466
83 + 31595383 = 31595466
103 + 31595363 = 31595466
193 + 31595273 = 31595466
223 + 31595243 = 31595466
229 + 31595237 = 31595466

Showing the first eight; more decompositions exist.
