Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494382, here are decompositions:

89 + 31494293 = 31494382
239 + 31494143 = 31494382
263 + 31494119 = 31494382
383 + 31493999 = 31494382
431 + 31493951 = 31494382
593 + 31493789 = 31494382
599 + 31493783 = 31494382
809 + 31493573 = 31494382

Showing the first eight; more decompositions exist.
