Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101042, here are decompositions:

43 + 100999 = 101042
61 + 100981 = 101042
241 + 100801 = 101042
349 + 100693 = 101042
373 + 100669 = 101042
421 + 100621 = 101042
433 + 100609 = 101042
523 + 100519 = 101042

Showing the first eight; more decompositions exist.
