Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100542, here are decompositions:

5 + 100537 = 100542
19 + 100523 = 100542
23 + 100519 = 100542
31 + 100511 = 100542
41 + 100501 = 100542
59 + 100483 = 100542
73 + 100469 = 100542
83 + 100459 = 100542

Showing the first eight; more decompositions exist.
