Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447382, here are decompositions:

3 + 31447379 = 31447382
19 + 31447363 = 31447382
193 + 31447189 = 31447382
283 + 31447099 = 31447382
313 + 31447069 = 31447382
409 + 31446973 = 31447382
433 + 31446949 = 31447382
523 + 31446859 = 31447382

Showing the first eight; more decompositions exist.
