Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504318, here are decompositions:

89 + 31504229 = 31504318
191 + 31504127 = 31504318
281 + 31504037 = 31504318
347 + 31503971 = 31504318
389 + 31503929 = 31504318
401 + 31503917 = 31504318
431 + 31503887 = 31504318
509 + 31503809 = 31504318

Showing the first eight; more decompositions exist.
