Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504132, here are decompositions:

3 + 31504129 = 31504132
5 + 31504127 = 31504132
29 + 31504103 = 31504132
269 + 31503863 = 31504132
353 + 31503779 = 31504132
383 + 31503749 = 31504132
419 + 31503713 = 31504132
563 + 31503569 = 31504132

Showing the first eight; more decompositions exist.
