Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476558, here are decompositions:

7 + 31476551 = 31476558
11 + 31476547 = 31476558
41 + 31476517 = 31476558
59 + 31476499 = 31476558
97 + 31476461 = 31476558
101 + 31476457 = 31476558
107 + 31476451 = 31476558
109 + 31476449 = 31476558

Showing the first eight; more decompositions exist.
