Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470744, here are decompositions:

23 + 31470721 = 31470744
43 + 31470701 = 31470744
83 + 31470661 = 31470744
103 + 31470641 = 31470744
163 + 31470581 = 31470744
181 + 31470563 = 31470744
197 + 31470547 = 31470744
421 + 31470323 = 31470744

Showing the first eight; more decompositions exist.
