Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152520, here are decompositions:

19 + 152501 = 152520
59 + 152461 = 152520
61 + 152459 = 152520
79 + 152441 = 152520
97 + 152423 = 152520
101 + 152419 = 152520
103 + 152417 = 152520
113 + 152407 = 152520

Showing the first eight; more decompositions exist.
