Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472576, here are decompositions:

97 + 31472479 = 31472576
127 + 31472449 = 31472576
139 + 31472437 = 31472576
283 + 31472293 = 31472576
337 + 31472239 = 31472576
367 + 31472209 = 31472576
397 + 31472179 = 31472576
409 + 31472167 = 31472576

Showing the first eight; more decompositions exist.
