Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494194, here are decompositions:

37 + 31494157 = 31494194
97 + 31494097 = 31494194
103 + 31494091 = 31494194
211 + 31493983 = 31494194
313 + 31493881 = 31494194
337 + 31493857 = 31494194
373 + 31493821 = 31494194
541 + 31493653 = 31494194

Showing the first eight; more decompositions exist.
