Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509734, here are decompositions:

37 + 31509697 = 31509734
43 + 31509691 = 31509734
73 + 31509661 = 31509734
163 + 31509571 = 31509734
181 + 31509553 = 31509734
211 + 31509523 = 31509734
331 + 31509403 = 31509734
397 + 31509337 = 31509734

Showing the first eight; more decompositions exist.
