Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482704, here are decompositions:

37 + 31482667 = 31482704
61 + 31482643 = 31482704
73 + 31482631 = 31482704
193 + 31482511 = 31482704
277 + 31482427 = 31482704
367 + 31482337 = 31482704
397 + 31482307 = 31482704
433 + 31482271 = 31482704

Showing the first eight; more decompositions exist.
