Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462648, here are decompositions:

59 + 31462589 = 31462648
71 + 31462577 = 31462648
101 + 31462547 = 31462648
167 + 31462481 = 31462648
197 + 31462451 = 31462648
359 + 31462289 = 31462648
431 + 31462217 = 31462648
521 + 31462127 = 31462648

Showing the first eight; more decompositions exist.
