Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494082, here are decompositions:

3 + 31494079 = 31494082
29 + 31494053 = 31494082
41 + 31494041 = 31494082
83 + 31493999 = 31494082
131 + 31493951 = 31494082
173 + 31493909 = 31494082
293 + 31493789 = 31494082
509 + 31493573 = 31494082

Showing the first eight; more decompositions exist.
