Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535542, here are decompositions:

113 + 31535429 = 31535542
131 + 31535411 = 31535542
359 + 31535183 = 31535542
419 + 31535123 = 31535542
461 + 31535081 = 31535542
509 + 31535033 = 31535542
743 + 31534799 = 31535542
911 + 31534631 = 31535542

Showing the first eight; more decompositions exist.
