Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494404, here are decompositions:

3 + 31494401 = 31494404
103 + 31494301 = 31494404
157 + 31494247 = 31494404
163 + 31494241 = 31494404
307 + 31494097 = 31494404
313 + 31494091 = 31494404
421 + 31493983 = 31494404
463 + 31493941 = 31494404

Showing the first eight; more decompositions exist.
