Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100570, here are decompositions:

11 + 100559 = 100570
23 + 100547 = 100570
47 + 100523 = 100570
53 + 100517 = 100570
59 + 100511 = 100570
101 + 100469 = 100570
167 + 100403 = 100570
179 + 100391 = 100570

Showing the first eight; more decompositions exist.
