Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472544, here are decompositions:

7 + 31472537 = 31472544
43 + 31472501 = 31472544
107 + 31472437 = 31472544
193 + 31472351 = 31472544
251 + 31472293 = 31472544
283 + 31472261 = 31472544
353 + 31472191 = 31472544
401 + 31472143 = 31472544

Showing the first eight; more decompositions exist.
