Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502418, here are decompositions:

47 + 31502371 = 31502418
89 + 31502329 = 31502418
107 + 31502311 = 31502418
131 + 31502287 = 31502418
139 + 31502279 = 31502418
149 + 31502269 = 31502418
229 + 31502189 = 31502418
257 + 31502161 = 31502418

Showing the first eight; more decompositions exist.
