Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504328, here are decompositions:

109 + 31504219 = 31504328
127 + 31504201 = 31504328
139 + 31504189 = 31504328
199 + 31504129 = 31504328
241 + 31504087 = 31504328
277 + 31504051 = 31504328
367 + 31503961 = 31504328
397 + 31503931 = 31504328

Showing the first eight; more decompositions exist.
