Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552042, here are decompositions:

23 + 31552019 = 31552042
83 + 31551959 = 31552042
101 + 31551941 = 31552042
239 + 31551803 = 31552042
359 + 31551683 = 31552042
443 + 31551599 = 31552042
449 + 31551593 = 31552042
503 + 31551539 = 31552042

Showing the first eight; more decompositions exist.
