Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474862, here are decompositions:

61 + 31474801 = 31474862
79 + 31474783 = 31474862
193 + 31474669 = 31474862
313 + 31474549 = 31474862
373 + 31474489 = 31474862
439 + 31474423 = 31474862
499 + 31474363 = 31474862
571 + 31474291 = 31474862

Showing the first eight; more decompositions exist.
