Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494244, here are decompositions:

3 + 31494241 = 31494244
83 + 31494161 = 31494244
101 + 31494143 = 31494244
191 + 31494053 = 31494244
293 + 31493951 = 31494244
317 + 31493927 = 31494244
461 + 31493783 = 31494244
797 + 31493447 = 31494244

Showing the first eight; more decompositions exist.
