Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945242, here are decompositions:

31 + 945211 = 945242
139 + 945103 = 945242
211 + 945031 = 945242
313 + 944929 = 945242
349 + 944893 = 945242
409 + 944833 = 945242
421 + 944821 = 945242
439 + 944803 = 945242

Showing the first eight; more decompositions exist.
