Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942142, here are decompositions:

29 + 942113 = 942142
41 + 942101 = 942142
101 + 942041 = 942142
239 + 941903 = 942142
263 + 941879 = 942142
281 + 941861 = 942142
389 + 941753 = 942142
401 + 941741 = 942142

Showing the first eight; more decompositions exist.
