Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507452, here are decompositions:

89 + 31507363 = 31507452
101 + 31507351 = 31507452
131 + 31507321 = 31507452
181 + 31507271 = 31507452
241 + 31507211 = 31507452
271 + 31507181 = 31507452
293 + 31507159 = 31507452
313 + 31507139 = 31507452

Showing the first eight; more decompositions exist.
