Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20750, here are decompositions:

3 + 20747 = 20750
7 + 20743 = 20750
19 + 20731 = 20750
31 + 20719 = 20750
43 + 20707 = 20750
109 + 20641 = 20750
139 + 20611 = 20750
151 + 20599 = 20750

Showing the first eight; more decompositions exist.
