Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507024, here are decompositions:

47 + 31506977 = 31507024
113 + 31506911 = 31507024
137 + 31506887 = 31507024
233 + 31506791 = 31507024
281 + 31506743 = 31507024
347 + 31506677 = 31507024
383 + 31506641 = 31507024
503 + 31506521 = 31507024

Showing the first eight; more decompositions exist.
