Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504566, here are decompositions:

19 + 31504547 = 31504566
73 + 31504493 = 31504566
113 + 31504453 = 31504566
127 + 31504439 = 31504566
179 + 31504387 = 31504566
193 + 31504373 = 31504566
199 + 31504367 = 31504566
239 + 31504327 = 31504566

Showing the first eight; more decompositions exist.
