Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31451062, here are decompositions:

29 + 31451033 = 31451062
101 + 31450961 = 31451062
113 + 31450949 = 31451062
233 + 31450829 = 31451062
239 + 31450823 = 31451062
281 + 31450781 = 31451062
443 + 31450619 = 31451062
449 + 31450613 = 31451062

Showing the first eight; more decompositions exist.
