Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476578, here are decompositions:

31 + 31476547 = 31476578
61 + 31476517 = 31476578
79 + 31476499 = 31476578
127 + 31476451 = 31476578
229 + 31476349 = 31476578
409 + 31476169 = 31476578
421 + 31476157 = 31476578
547 + 31476031 = 31476578

Showing the first eight; more decompositions exist.
