Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541434, here are decompositions:

5 + 31541429 = 31541434
17 + 31541417 = 31541434
137 + 31541297 = 31541434
167 + 31541267 = 31541434
191 + 31541243 = 31541434
293 + 31541141 = 31541434
317 + 31541117 = 31541434
383 + 31541051 = 31541434

Showing the first eight; more decompositions exist.
