Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537342, here are decompositions:

3 + 31537339 = 31537342
29 + 31537313 = 31537342
71 + 31537271 = 31537342
113 + 31537229 = 31537342
191 + 31537151 = 31537342
293 + 31537049 = 31537342
359 + 31536983 = 31537342
383 + 31536959 = 31537342

Showing the first eight; more decompositions exist.
