Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500152, here are decompositions:

3 + 31500149 = 31500152
163 + 31499989 = 31500152
349 + 31499803 = 31500152
421 + 31499731 = 31500152
661 + 31499491 = 31500152
751 + 31499401 = 31500152
769 + 31499383 = 31500152
811 + 31499341 = 31500152

Showing the first eight; more decompositions exist.
