Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501274, here are decompositions:

43 + 31501231 = 31501274
73 + 31501201 = 31501274
157 + 31501117 = 31501274
193 + 31501081 = 31501274
307 + 31500967 = 31501274
421 + 31500853 = 31501274
457 + 31500817 = 31501274
787 + 31500487 = 31501274

Showing the first eight; more decompositions exist.
