Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503064, here are decompositions:

3 + 31503061 = 31503064
11 + 31503053 = 31503064
71 + 31502993 = 31503064
101 + 31502963 = 31503064
137 + 31502927 = 31503064
167 + 31502897 = 31503064
503 + 31502561 = 31503064
701 + 31502363 = 31503064

Showing the first eight; more decompositions exist.
