Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504226, here are decompositions:

7 + 31504219 = 31504226
37 + 31504189 = 31504226
43 + 31504183 = 31504226
97 + 31504129 = 31504226
139 + 31504087 = 31504226
373 + 31503853 = 31504226
379 + 31503847 = 31504226
499 + 31503727 = 31504226

Showing the first eight; more decompositions exist.
