Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494088, here are decompositions:

5 + 31494083 = 31494088
47 + 31494041 = 31494088
89 + 31493999 = 31494088
137 + 31493951 = 31494088
179 + 31493909 = 31494088
569 + 31493519 = 31494088
641 + 31493447 = 31494088
797 + 31493291 = 31494088

Showing the first eight; more decompositions exist.
