Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476782, here are decompositions:

79 + 31476703 = 31476782
151 + 31476631 = 31476782
283 + 31476499 = 31476782
331 + 31476451 = 31476782
349 + 31476433 = 31476782
409 + 31476373 = 31476782
433 + 31476349 = 31476782
439 + 31476343 = 31476782

Showing the first eight; more decompositions exist.
