Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460542, here are decompositions:

5 + 31460537 = 31460542
59 + 31460483 = 31460542
101 + 31460441 = 31460542
173 + 31460369 = 31460542
251 + 31460291 = 31460542
263 + 31460279 = 31460542
479 + 31460063 = 31460542
593 + 31459949 = 31460542

Showing the first eight; more decompositions exist.
