Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525842, here are decompositions:

3 + 525839 = 525842
61 + 525781 = 525842
73 + 525769 = 525842
103 + 525739 = 525842
193 + 525649 = 525842
271 + 525571 = 525842
313 + 525529 = 525842
349 + 525493 = 525842

Showing the first eight; more decompositions exist.
