Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482772, here are decompositions:

11 + 31482761 = 31482772
29 + 31482743 = 31482772
89 + 31482683 = 31482772
131 + 31482641 = 31482772
173 + 31482599 = 31482772
263 + 31482509 = 31482772
383 + 31482389 = 31482772
479 + 31482293 = 31482772

Showing the first eight; more decompositions exist.
