Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504470, here are decompositions:

17 + 31504453 = 31504470
31 + 31504439 = 31504470
83 + 31504387 = 31504470
97 + 31504373 = 31504470
103 + 31504367 = 31504470
113 + 31504357 = 31504470
167 + 31504303 = 31504470
241 + 31504229 = 31504470

Showing the first eight; more decompositions exist.
