Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151100, here are decompositions:

43 + 151057 = 151100
73 + 151027 = 151100
109 + 150991 = 151100
139 + 150961 = 151100
181 + 150919 = 151100
193 + 150907 = 151100
199 + 150901 = 151100
211 + 150889 = 151100

Showing the first eight; more decompositions exist.
