Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504330, here are decompositions:

3 + 31504327 = 31504330
101 + 31504229 = 31504330
197 + 31504133 = 31504330
227 + 31504103 = 31504330
233 + 31504097 = 31504330
293 + 31504037 = 31504330
317 + 31504013 = 31504330
353 + 31503977 = 31504330

Showing the first eight; more decompositions exist.
