Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504550, here are decompositions:

3 + 31504547 = 31504550
97 + 31504453 = 31504550
163 + 31504387 = 31504550
193 + 31504357 = 31504550
199 + 31504351 = 31504550
223 + 31504327 = 31504550
331 + 31504219 = 31504550
349 + 31504201 = 31504550

Showing the first eight; more decompositions exist.
