Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504192, here are decompositions:

3 + 31504189 = 31504192
59 + 31504133 = 31504192
89 + 31504103 = 31504192
179 + 31504013 = 31504192
263 + 31503929 = 31504192
281 + 31503911 = 31504192
383 + 31503809 = 31504192
443 + 31503749 = 31504192

Showing the first eight; more decompositions exist.
