Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476452, here are decompositions:

3 + 31476449 = 31476452
19 + 31476433 = 31476452
61 + 31476391 = 31476452
79 + 31476373 = 31476452
103 + 31476349 = 31476452
109 + 31476343 = 31476452
283 + 31476169 = 31476452
379 + 31476073 = 31476452

Showing the first eight; more decompositions exist.
