Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494230, here are decompositions:

73 + 31494157 = 31494230
139 + 31494091 = 31494230
151 + 31494079 = 31494230
241 + 31493989 = 31494230
331 + 31493899 = 31494230
349 + 31493881 = 31494230
373 + 31493857 = 31494230
379 + 31493851 = 31494230

Showing the first eight; more decompositions exist.
