Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477282, here are decompositions:

101 + 31477181 = 31477282
401 + 31476881 = 31477282
461 + 31476821 = 31477282
659 + 31476623 = 31477282
773 + 31476509 = 31477282
821 + 31476461 = 31477282
911 + 31476371 = 31477282
929 + 31476353 = 31477282

Showing the first eight; more decompositions exist.
