Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101512, here are decompositions:

11 + 101501 = 101512
23 + 101489 = 101512
29 + 101483 = 101512
83 + 101429 = 101512
101 + 101411 = 101512
113 + 101399 = 101512
149 + 101363 = 101512
179 + 101333 = 101512

Showing the first eight; more decompositions exist.
