Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504282, here are decompositions:

53 + 31504229 = 31504282
149 + 31504133 = 31504282
179 + 31504103 = 31504282
269 + 31504013 = 31504282
311 + 31503971 = 31504282
353 + 31503929 = 31504282
419 + 31503863 = 31504282
503 + 31503779 = 31504282

Showing the first eight; more decompositions exist.
