Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152900, here are decompositions:

3 + 152897 = 152900
43 + 152857 = 152900
61 + 152839 = 152900
67 + 152833 = 152900
79 + 152821 = 152900
109 + 152791 = 152900
229 + 152671 = 152900
271 + 152629 = 152900

Showing the first eight; more decompositions exist.
