Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493434, here are decompositions:

113 + 31493321 = 31493434
233 + 31493201 = 31493434
263 + 31493171 = 31493434
281 + 31493153 = 31493434
443 + 31492991 = 31493434
491 + 31492943 = 31493434
587 + 31492847 = 31493434
593 + 31492841 = 31493434

Showing the first eight; more decompositions exist.
