Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503184, here are decompositions:

3 + 31503181 = 31503184
5 + 31503179 = 31503184
17 + 31503167 = 31503184
131 + 31503053 = 31503184
191 + 31502993 = 31503184
257 + 31502927 = 31503184
701 + 31502483 = 31503184
743 + 31502441 = 31503184

Showing the first eight; more decompositions exist.
