Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476428, here are decompositions:

37 + 31476391 = 31476428
79 + 31476349 = 31476428
241 + 31476187 = 31476428
271 + 31476157 = 31476428
331 + 31476097 = 31476428
397 + 31476031 = 31476428
499 + 31475929 = 31476428
601 + 31475827 = 31476428

Showing the first eight; more decompositions exist.
