Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482746, here are decompositions:

3 + 31482743 = 31482746
37 + 31482709 = 31482746
79 + 31482667 = 31482746
103 + 31482643 = 31482746
307 + 31482439 = 31482746
397 + 31482349 = 31482746
409 + 31482337 = 31482746
439 + 31482307 = 31482746

Showing the first eight; more decompositions exist.
