Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502044, here are decompositions:

107 + 31501937 = 31502044
131 + 31501913 = 31502044
137 + 31501907 = 31502044
263 + 31501781 = 31502044
293 + 31501751 = 31502044
317 + 31501727 = 31502044
383 + 31501661 = 31502044
461 + 31501583 = 31502044

Showing the first eight; more decompositions exist.
