Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456152, here are decompositions:

29 + 31456123 = 31456152
31 + 31456121 = 31456152
53 + 31456099 = 31456152
59 + 31456093 = 31456152
73 + 31456079 = 31456152
131 + 31456021 = 31456152
139 + 31456013 = 31456152
149 + 31456003 = 31456152

Showing the first eight; more decompositions exist.
