Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494214, here are decompositions:

53 + 31494161 = 31494214
71 + 31494143 = 31494214
131 + 31494083 = 31494214
173 + 31494041 = 31494214
263 + 31493951 = 31494214
431 + 31493783 = 31494214
503 + 31493711 = 31494214
641 + 31493573 = 31494214

Showing the first eight; more decompositions exist.
