Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504360, here are decompositions:

3 + 31504357 = 31504360
131 + 31504229 = 31504360
227 + 31504133 = 31504360
233 + 31504127 = 31504360
257 + 31504103 = 31504360
263 + 31504097 = 31504360
347 + 31504013 = 31504360
383 + 31503977 = 31504360

Showing the first eight; more decompositions exist.
