Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494350, here are decompositions:

3 + 31494347 = 31494350
103 + 31494247 = 31494350
109 + 31494241 = 31494350
193 + 31494157 = 31494350
271 + 31494079 = 31494350
367 + 31493983 = 31494350
409 + 31493941 = 31494350
499 + 31493851 = 31494350

Showing the first eight; more decompositions exist.
