Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504162, here are decompositions:

29 + 31504133 = 31504162
59 + 31504103 = 31504162
149 + 31504013 = 31504162
191 + 31503971 = 31504162
233 + 31503929 = 31504162
251 + 31503911 = 31504162
353 + 31503809 = 31504162
383 + 31503779 = 31504162

Showing the first eight; more decompositions exist.
