Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31451622, here are decompositions:

5 + 31451617 = 31451622
43 + 31451579 = 31451622
61 + 31451561 = 31451622
73 + 31451549 = 31451622
101 + 31451521 = 31451622
131 + 31451491 = 31451622
239 + 31451383 = 31451622
353 + 31451269 = 31451622

Showing the first eight; more decompositions exist.
