Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152990, here are decompositions:

31 + 152959 = 152990
37 + 152953 = 152990
43 + 152947 = 152990
139 + 152851 = 152990
151 + 152839 = 152990
157 + 152833 = 152990
181 + 152809 = 152990
199 + 152791 = 152990

Showing the first eight; more decompositions exist.
