Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537382, here are decompositions:

43 + 31537339 = 31537382
73 + 31537309 = 31537382
109 + 31537273 = 31537382
139 + 31537243 = 31537382
181 + 31537201 = 31537382
229 + 31537153 = 31537382
379 + 31537003 = 31537382
439 + 31536943 = 31537382

Showing the first eight; more decompositions exist.
