Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504556, here are decompositions:

103 + 31504453 = 31504556
199 + 31504357 = 31504556
229 + 31504327 = 31504556
337 + 31504219 = 31504556
367 + 31504189 = 31504556
373 + 31504183 = 31504556
673 + 31503883 = 31504556
709 + 31503847 = 31504556

Showing the first eight; more decompositions exist.
